company which we believe are within the meaning of the Private Securities
Litigation Reform Act of 1995. These forward-looking statements include
information in this document regarding the financial condition, results of
operations and business of Hudson River following the consummation of the
merger. They also include statements relating to the synergies, efficiencies,
cost savings and funding advantages that are expected to be realized from the
merger and the expected impact of the merger on Hudson River's financial
performance and earnings estimates for the combined company. Forward-looking
statements are also identified by words such as "believes," "anticipates,"

Forward-looking statements involve certain risks and uncertainties. You should
understand that the following important factors, in addition to those discussed
elsewhere in this document and in the documents which are incorporated into this
document by reference, could affect the future results of Hudson River and
Cohoes, and of Hudson River after the merger and could cause those results to
differ materially from those expressed in our forward-looking statements:

     o    expected cost savings from the merger may not be fully realized or may
          not be realized within the expected time frame;

     o    revenues following the merger may be lower than expected, or
          withdrawals of customer deposits, operating costs, customer loss and
          business disruption following the merger may be greater than expected;

     o    costs or difficulties related to the integration of the businesses of
          Hudson River and Cohoes may be greater than expected;

     o    changes in the interest rate environment may reduce margins more than
          expected;

     o    general economic conditions, either nationally or regionally, may be
          less favorable than expected, resulting in, among other things, a
          deterioration in the credit quality of our loans;

     o    legislative or regulatory changes may adversely affect the business in
          which we are engaged;

     o    the willingness of users to substitute our products and services for
          competitors' products and services may be less than expected; and

     o    competitive pressure in the banking industry, and in particular our
          regional market, may increase.

Hudson River after the merger is included in the SEC filings incorporated by

                                   THE MERGER

This summary of the terms of the merger may not contain all the information that
is important to you. You should read the full text of the merger agreement which
is attached as Appendix A. This summary is qualified in its entirety by
reference to the merger agreement.

Overview of the Merger

Cohoes will be merged into Hudson River. Hudson River will be the surviving
entity of the merger, but its name will be changed to "Cohoes-Hudson Bancorp,
Inc." Each outstanding share of Cohoes common stock will be converted into the
right to receive 1.185 shares of Hudson River common stock. After this merger of
equals, current Hudson River shareholders will own approximately 62% of the
combined company and current Cohoes shareholders will own the remainder.

Merger Consideration

Each outstanding share of Cohoes common stock will be converted into the right
to receive 1.185 shares of Hudson River common stock. No fractional shares of
Hudson River common stock will be issued in the merger. Instead of a fractional
share, you will receive the cash value (without interest) of the fractional
share based on the closing price of Hudson River common stock on the last
trading day before the merger.

On ___________, 2000, Hudson River common stock closed at $______ per share.
Based on that price, the value of 1.185 shares of Hudson River common stock
would have been approximately $__________ and the aggregate market value of the
merger consideration would have been approximately $____________. These values,
however, may increase or decrease as a result of fluctuations in the market
price of Hudson River common stock.

Each outstanding option to purchase shares of Cohoes common stock will be
converted into an option to purchase 1.185 times as many shares of Hudson River
common stock. The per share exercise price will be divided by 1.185, but the
other terms and conditions of the converted option will not change. Fractional
shares will be rounded to the nearest whole share and per share exercise prices
will be rounded to the nearest whole cent. Options for 860,555 shares of Cohoes
common stock were outstanding on July ___, 2000.

Background of the Merger

Over the last several years the financial services industry has become
increasingly competitive and has undergone industry-wide consolidation. The
market in which Hudson River and Cohoes operate has been affected by this trend,
experiencing a period of rapid acquisition and consolidation that has affected
many of the banks and thrift institutions. In addition, large financial
institutions have entered this market through acquisitions of local financial
institutions. In response to these developments, the board of each of Hudson
River and Cohoes has, on an ongoing basis, considered strategic options for
increasing shareholder value, including potential acquisitions of other
institutions.

At a trade association meeting during the summer of 1999, the chief executive
officers of each of Hudson River and Cohoes discussed the possibility of
increasing shareholder value through a merger of equals of the two companies. On
the basis of this discussion, the chief financial officers of each company met
on August 3, 1999 to further explore the possibility of a business combination.
From January through March of 2000, the two chief executive officers met several
more times to explore common ground and discuss the possible terms of a merger
of equals.

On April 13, 2000, the Cohoes board formally authorized retaining Keefe Bruyette
& Woods, Inc. to act as Cohoes' financial advisor in connection with the
proposed business combination. Keefe, Bruyette & Woods, Inc. has provided
general merger and acquisition advisory services to Cohoes since the completion
of Cohoes' initial public offering in December, 1998. On April 6, 2000, the
Hudson River board authorized retaining Sandler O'Neill & Partners, L.P. to act
as Hudson River's financial advisor in connection with the proposed business
combination. Each financial advisor made an independent analysis of the
proposal. See "Opinion of Hudson River's Financial Advisor" on page __ and
"Opinion of Cohoes' Financial Advisor" on page ___.

On April 13, 2000, the boards of each company met and considered the terms of
the proposed transaction. After consultation with each company's executive
officers and financial advisors, the consensus of each board was to move ahead
with the transaction. During the period from April 14 to April 25, 2000, the
parties negotiated the terms of the merger agreement and completed their
respective due diligence efforts.

On April 25, 2000, the board of each company met with their respective financial
advisors and special counsel to review the financial and legal arrangements of
the definitive agreement. After careful consultation, each board authorized the
execution of the merger agreement. Following the conclusion of the board
meetings, Hudson River and Cohoes executed and delivered the merger agreement
and the stock option agreements. Each director of both companies also executed a
voting agreement obligating them to vote for the adoption of the merger
agreement.

Subsequent to April 25, 2000, after the merger had been publicly announced, each
of Hudson River and Cohoes received an unsolicited acquisition proposal from
TrustCo Bank Corp NY. The proposals were exchange offers of TrustCo's common
stock equal to $14.00 per Hudson River share and $16.00 per Cohoes share. The
unsolicited TrustCo proposals were each contingent upon, among other factors,
Hudson River and Cohoes terminating its merger of equals agreement with the
other party. A week later, Cohoes received an unsolicited acquisition proposal
from Ambanc Holding Company, Inc. This proposal was a cash offer of $14.75 for
each share of Cohoes common stock. Ambanc subsequently increased its proposal to
$15.25 per share in cash and indicated that it would be willing to have the
consideration paid in a combination of cash and stock. After considering their
duties and responsibilities to shareholders, including the price of each
proposal, the respective boards of directors of Hudson River and Cohoes each
decided not to pursue any discussions with the third parties making the
proposals.

Hudson River's Reasons for the Merger

Hudson River believes that the merger will:

     o    create a dominant franchise with assets of approximately $1.8 billion
          and a market capitalization of approximately $275 million, based on
          recent market prices;

     o    create opportunities for significant operational benefits and
          financial cost savings and revenue enhancements through the
          integration of Hudson River's and Cohoes' operations;

     o    be immediately accretive to earnings per share estimated to be 13%
          accretive to Hudson River's earnings per share, and significantly
          enhance the combined company's future earnings per share growth rate;

     o    expand its core market area and create critical mass in upstate New
          York with a strong local presence;

     o    strengthen its competitive and capital position in the financial
          services industry, which is rapidly changing and growing more
          competitive; and

     o    provide an additional platform for further growth.

The Hudson River board has determined that the terms of the merger and the
merger agreement and the issuance of Hudson River common stock in connection
with the merger are advisable and fair to, and in the best interests of, Hudson
River and its shareholders. In reaching its determination, the Hudson River
board considered the opinion of its financial advisor with respect to the
fairness of the exchange ratio from a financial point of view. In arriving at
its determination, the Hudson River board also considered a number of factors,
including that the merger should produce a well capitalized institution with an
enhanced retail lending franchise as well as a number of financial benefits that
should foster the potential for earnings growth. The Hudson River board did not
assign any specific or relative weights to the factors considered, and
individual directors may have given different weights to different factors. The
material factors considered were as follows:

     o    Information concerning the businesses, earnings, operations, financial
          condition, prospects, capital levels and asset quality of Cohoes,
          individually and as combined with Hudson River.

     o    The opinion rendered by Hudson River's financial advisor that as of
          the date of the opinion the exchange ratio was fair, from a financial
          point of view, to the holders of Hudson River common stock. See
          "--Opinion of Hudson River's Financial Advisor" for the assumptions
          made in connection with, and limitations on, such opinion.

     o    The terms of the merger agreement, the stock option agreements and the
          other documents executed in connection with the merger. See "The
          Merger."

     o    The anticipated cost savings available to the combined company as a
          result of the merger totaling approximately $3.6 million, consisting
          of savings in (1) salaries and benefits of approximately $1.7 million;
          (2) occupancy expense of approximately $104,000; (3) ESOP expense of
          approximately $616,000; and (4) other operating expenses of $1.2
          million.

     o    The current and prospective economic, competitive and regulatory
          environment facing each institution and financial institutions
          generally.

     o    The results of the due diligence investigation conducted by the
          management of Hudson River, including assessment of credit policies,
          asset quality, interest rate risk, litigation and adequacy of loan
          loss reserves.

     o    The expectation that the merger would be tax-free to Hudson River and
          its shareholders for federal income tax purposes. See "-- Federal
          Income Tax Consequences of the Merger."

     o    The ability to continue to enhance shareholder value through stock
          repurchase programs since the merger will be accounted for as a
          purchase.

     o    The existence of the reciprocal stock option agreements, which might
          discourage third parties from seeking to acquire Hudson River by
          increasing the cost of such an acquisition and which might also
          preclude any third party from being able to effect a merger with
          Hudson River that would qualify for "pooling-of-interests" accounting
          treatment.

     o    The prospects for growth and expanded products and services, and other
          anticipated impacts on depositors, employees, customers and
          communities served by Hudson River and Cohoes, respectively.

     o    Additional revenue enhancement opportunities including (1) incremental
          earnings potential through the ability to leverage excess capital; (2)
          trust services; (3) expansion of small business lending; (4) cash
          management services; and (5) expanded legal lending limit.

Hudson River's board unanimously recommends to its shareholders that they vote
"FOR" adoption of the merger agreement and approval of the issuance of shares of
Hudson River common stock in the merger.

Cohoes' Reasons for the Merger

The Cohoes board of directors believes that the merger presents a unique
opportunity to combine two strong companies to create a dominant franchise in
the greater Albany, New York region with a commitment and the resources to
significantly enhance shareholder value.

In deciding to approve the merger agreement, the stock option agreement and the
transactions contemplated by such agreements, the Cohoes board considered the
following material factors:

     o    The Cohoes board's familiarity with and review of Cohoes' business,
          operations, earnings, prospects, financial condition, asset quality,
          and capital levels.

     o    The Cohoes board's review of the business, operations, prospects,
          earnings, financial condition, asset quality and capital levels of
          Hudson River on both an historical and a prospective basis. The Cohoes
          board considered the results of the due diligence investigation
          conducted by Cohoes' management and legal and

                                       13

<PAGE>



          financial advisors, including, among other things, assessments of
          Hudson River's credit policies, asset quality, interest rate risk and
          adequacy of loan loss reserves.

     o    The opportunities for expense reductions, operating efficiencies and
          revenue enhancements in the combined entity, including the belief of
          both parties that the merger will be immediately accretive to earnings
          per share, estimated to be 16% accretive to Cohoes' earnings per
          share, and significantly enhance the combined company's future
          earnings per share growth rate.

     o    The respective contributions of each party to the combined entity,
          including the 38% equity position that the Cohoes shareholders would
          have in the combined entity.

     o    The presentation of Keefe, Bruyette & Woods, Inc., to the Cohoes board
          and the opinion of Keefe, Bruyette & Woods, Inc., rendered on April
          25, 2000, that, as of that date and based upon and subject to the
          procedures followed, assumptions made, matters considered, and
          limitations on the analyses undertaken, the exchange ratio was fair,
          from a financial point of view, to the Cohoes shareholders. For a
          discussion of the opinion of Keefe, Bruyette & Woods, Inc., see "-
          Opinion of Cohoes' Financial Advisor."

     o    The complementary nature of the businesses, business strategies,
          cultures and products of Cohoes and Hudson River, including the fact
          that Cohoes' core deposits would enhance the combined organization's
          deposit mix.

     o    The merger is expected to be tax-free for Cohoes for federal income
          tax purposes as well as to Cohoes shareholders (except for cash paid
          in lieu of fractional shares). See "-- Federal Income Tax Consequences
          of the Merger."

     o    The nature of, and likelihood of obtaining, the regulatory approvals
          that would be required with respect to the merger. See "-- Regulatory
          Matters." The Cohoes board also considered the nature and scope of the
          conditions to the merger and the likelihood of these conditions being
          satisfied.

     o    The existence of the reciprocal stock option agreements, which might
          discourage third parties from seeking to acquire Cohoes by increasing
          the cost of such an acquisition and which might also preclude any
          third party from being able to effect a merger with Cohoes that would
          qualify for "pooling-of-interests" accounting treatment.

     o    The non-financial terms of the merger agreement, including that Cohoes
          will have equal representation on the board of directors of Hudson
          River, that the President and Chief Executive Officer of Cohoes will
          be the Chairman and Chief Executive Officer of the combined company,
          and that the name of the combined company will be Cohoes-Hudson
          Bancorp, Inc.

     o    The current and prospective economic and competitive environment
          facing the financial services industry generally, and Cohoes in
          particular, including the continued rapid consolidation in the
          industry and the increasing importance of operational scale and
          financial resources in maintaining efficiency and remaining
          competitive over the long term and in being able to capitalize on
          technological developments which significantly impact industry
          competition.

The Cohoes board has determined that the terms of the merger and the merger
agreement are fair to, and in the best interests of, Cohoes and its
shareholders. In reaching its determination to approve and deem advisable the
merger agreement, and to approve the stock option agreement and the transactions
contemplated therein, the Cohoes board did not assign any relative or specific
weights to the various factors considered by it, and individual directors may
have given differing weights to different factors.

Cohoes' board of directors unanimously recommends that the holders of Cohoes
common stock vote "FOR" adoption of the Merger Agreement.

Opinion of Hudson River's Financial Advisor

By letter agreement dated as of April 13, 2000, Hudson River retained Sandler
O'Neill as an independent financial advisor in connection with Hudson River's
consideration of a possible business combination with Cohoes. Sandler O'Neill is
a nationally recognized investment banking firm whose principal business
specialty is financial institutions. In the ordinary course of its investment
banking business, Sandler O'Neill is regularly engaged in the valuation of
financial institutions and their securities in connection with mergers and
acquisitions and other corporate transactions.

Sandler O'Neill acted as financial advisor to Hudson River in connection with
the merger and participated in certain of the negotiations leading to the merger
agreement. At the request of the Hudson River Board, representatives of Sandler
O'Neill attended the April 25, 2000 meeting of the Hudson River Board at which
the Board considered and approved the merger agreement. At the meeting, Sandler
O'Neill delivered to the Hudson River Board its oral opinion, subsequently
confirmed in writing, that as of such date, the Exchange Ratio was fair to the
Hudson River shareholders from a financial point of view. Sandler O'Neill has
also delivered to the Hudson River Board a written opinion dated the date of
this proxy statement/prospectus (the "Sandler Opinion") which is substantially
identical to the April 25, 2000 opinion.

The full text of the Sandler Opinion is attached as Appendix B to this proxy
statement/prospectus. The Sandler Opinion outlines the procedures followed,
assumptions made, matters considered and qualifications and limitations on the
review undertaken by Sandler O'Neill in rendering the opinion. The Sandler
Opinion is incorporated by reference into this description of the opinion and
this description is qualified in its entirety by reference to the Sandler
Opinion. Hudson River shareholders are urged to carefully read the Sandler
Opinion in connection with their consideration of the proposed merger.

The Sandler Opinion was directed to the Hudson River Board and was provided to
Hudson River for its information in considering the merger. The Sandler Opinion
is directed only to the fairness of the Exchange Ratio to Hudson River
shareholders from a financial point of view. It does not address the underlying
business decision of Hudson River to engage in the merger or any other aspect of
the merger and is not a recommendation to any Hudson River shareholder as to how
such shareholder should vote at the Hudson River annual meeting with respect to
the merger or any other related matter.

In rendering its April 25, 2000 opinion, Sandler O'Neill performed a variety of
financial analyses. The following is a summary of the material analyses
performed by Sandler O'Neill, but is not a complete description of all the
analyses underlying Sandler O'Neill's opinion. The preparation of a fairness
opinion is a complex process involving subjective judgments as to the most
appropriate and relevant methods of financial analysis and the application of
those methods to the particular circumstances. The process, therefore, is not
necessarily susceptible to a partial analysis or summary description. Sandler
O'Neill believes that its analyses must be considered as a whole and that
selecting portions of the factors and analyses considered without considering
all factors and analyses, or attempting to ascribe relative weights to some or
all such factors and analyses, could create an incomplete view of the evaluation
process underlying its opinion. Also, no company included in Sandler O'Neill's
comparative analyses described below is identical to Hudson River or Cohoes and
no transaction is identical to the merger. Accordingly, an analysis of
comparable companies or transactions is not mathematical; rather, it involves
complex considerations and judgments concerning differences in financial, market
and operating characteristics of the companies and other factors that could
affect the public trading values or merger transaction values, as the case may
be, of Hudson River or Cohoes and the companies to which they are being
compared.

The earnings projections for Hudson River and Cohoes relied upon by Sandler
O'Neill in its analyses were reviewed with management and were based upon 2001
and 2002 internal projections of Hudson River and Cohoes provided to Sandler
O'Neill and on published I/B/E/S International consensus earnings estimates for
2001. For periods after 2002, Sandler O'Neill assumed an annual growth rate on
earning assets of 5.00%. The 2001 and 2002 earnings projections furnished to
Sandler O'Neill were prepared by the senior managements of Hudson River and
Cohoes for internal purposes only and not with a view towards public disclosure.
Those projections, as well as the other earnings estimates relied upon by
Sandler O'Neill in its analyses, were based on numerous variables and
assumptions which are inherently uncertain and accordingly, actual results could
vary materially from those set forth in such projections.

                                       15

<PAGE>



In performing its analyses, Sandler O'Neill also made numerous assumptions with
respect to industry performance, business and economic conditions and various
other matters, many of which cannot be predicted and are beyond the control of
Hudson River, Cohoes and Sandler O'Neill. The analyses performed by Sandler
O'Neill are not necessarily indicative of actual values or future results, which
may be significantly more or less favorable than suggested by such analyses.
Sandler O'Neill prepared its analyses solely for purposes of rendering its
opinion and provided such analyses to the Hudson River Board at the April 25th
meeting. Estimates on the values of companies do not purport to be appraisals or
necessarily reflect the prices at which companies or their securities may
actually be sold. Such estimates are inherently subject to uncertainty and
actual values may be materially different. Accordingly, Sandler O'Neill's
analyses do not necessarily reflect the value of Hudson River common stock or
the prices at which Hudson River common stock may be sold at any time.

Summary of Proposal. Sandler O'Neill reviewed the financial terms of the
proposed transaction. Based on the closing price of Hudson River common stock on
April 24, 2000 of $9.31 and an exchange ratio of 1.185, Sandler O'Neill
calculated an implied transaction value per share of Cohoes common stock of
$11.04. The implied aggregate transaction value was approximately $88 million.

Stock Trading History. Sandler O'Neill reviewed the history of the reported
trading prices and volume of Hudson River common stock and Cohoes common stock,
and the relationship between the movements in the prices of Hudson River common
stock and Cohoes common stock, respectively, to movements in certain stock
indices, including the Standard & Poor's 500 Index, the Nasdaq Bank Index, and
the median performance of a composite group of publicly traded regional savings
institutions selected by Sandler O'Neill. During the one year period ended April
20, 2000, both the Hudson River and Cohoes common stock outperformed the Nasdaq
Bank and composite indices, and underperformed the S&P Index.

Comparable Company Analysis. Sandler O'Neill used publicly available information
to compare selected financial and market trading information for Hudson River
and Cohoes and two groups of financial institutions selected by Sandler O'Neill.
The "Regional Group" consisted of Hudson River, Cohoes, and the following 13
publicly traded regional savings institutions:

Niagara Bancorp, Inc. (1)                 Flushing Financial Corp. (1)
WSFS Bancorp, Inc.                        Parkvale Financial Corp. (1)
PennFed Financial Services, Inc.          ESB Financial Corp.
OceanFirst Financial Corp. (1)            Troy Financial Corp.
GA Financial Inc.                         Provident Bancorp, Inc.
First Bell Bancorp, Inc. (1)              FMS Financial Corp.
Progress Financial Corp.

The "Highly Valued Group" consisted of the following 13 publicly traded savings
institutions which had a return on average equity (based on last twelve months'
earnings) of greater than 13.5% and a price-to-tangible book value of greater
than 134%.

First Financial Holdings Inc. (1)         First Federal Capital Corp. (1)
Queens County Bancorp Inc.                WSFS Financial Corp.
Andover Bancorp Inc. (1)                  First Essex Bancorp Inc. (1)
Medford Bancorp Inc. (1)                  People's Bancshares Inc.
First Bell Bancorp Inc. (1)               American Bank of Connecticut (1)
Progress Financial Corp.                  MetroWest Bank
Coastal Financial Corp.

The analysis compared publicly available financial information for Hudson River
and the median data for each of the Regional Group and Highly Valued Group as of
and for each of the years ended December 31, 1994 through 1998 and as of and for
the twelve months ended December 31, 1999 (or as of and for the twelve months
ended March 31, 2000 where noted).

Analysis of Selected Merger Transactions. Sandler O'Neill reviewed certain other
transactions involving publicly traded savings institutions with transaction
values greater than $15 million. Sandler O'Neill reviewed nine transactions
announced nationwide from January 1, 2000 to April 24, 2000 and three
transactions announced from January 1, 2000 to April 24, 2000 in the Mid
Atlantic and New England Regions. Sandler O'Neill also reviewed certain other
transactions involving publicly traded commercial banks and savings institutions
with transaction values greater than $15 million and less than $2 billion
involving mergers of equals. Sandler O'Neill reviewed twelve merger of equals
transactions announced nationwide for commercial banks and three merger of
equals transactions announced nationwide for savings institutions from January
1, 1998 to April 24, 2000. Sandler O'Neill reviewed and computed high, low ,
mean and median multiples and premiums for the respective groups of
transactions.

Discounted Dividend Stream and Terminal Value Analysis. Sandler O'Neill also
performed an analysis which estimated the future stream of after-tax dividend
flows of Hudson River through March 31, 2005 under various circumstances,
assuming Hudson River's current dividend payout ratio and that Hudson River
performed in accordance with the earnings forecasts reviewed with management. To
approximate the terminal value of Hudson River common stock at March 31, 2005,
Sandler O'Neill applied price/earnings multiples ranging from 8x to 19x and
applied multiples of tangible book value ranging from 50% to 175%. The dividend
income streams and terminal values were then discounted to present values using
different discount rates ranging from 9% to 15% chosen to reflect different
assumptions regarding required rates of return of holders or prospective buyers
of Hudson River common stock. As illustrated in the following table, this
analysis indicated an imputed range of values per share of Hudson River common
stock of $5.08 to $14.16 when applying the price/earnings multiples and $4.96 to
$19.23 when applying multiples of tangible book value.

Sandler O'Neill discussed the above ranges of multiples with the Hudson River
board of directors, with particular focus on transactions having price/earnings
multiples of between 10x and 14x, and on transactions having tangible book value
multiples of between .75x and 1.50x.

In connection with its analysis, Sandler O'Neill considered and discussed with
the Hudson River Board how the present value analysis would be affected by
changes in the underlying assumptions, including variations with respect to the
growth rate of assets, net interest spread, non-interest income, non-interest
expenses and dividend payout ratio. Sandler O'Neill noted that the discounted
dividend stream and terminal value analysis is a widely used valuation
methodology, but the results of such methodology are highly dependent upon the
numerous assumptions that must be made, and the results thereof are not
necessarily indicative of actual values or future results.

Contribution Analysis. Sandler O'Neill reviewed the relative contributions to,
among other things, total assets, total securities, total net loans, total
deposits, total borrowings, total equity and net income to be made by Hudson
River and Cohoes to the combined institution based on data at and for the
quarter ended March 31, 2000. This analysis indicated that Hudson River's
implied contribution was 62.0% of total assets, 71.4% of total securities, 58.2%
of total net loans, 60.0% of total deposits, 65.5% of total borrowings, 62.4% of
total equity, and 61.9% of last twelve months net income. Based upon an Exchange
Ratio of 1.185, holders of the Hudson River Common Stock would own approximately
60.1% of the fully diluted outstanding shares of the combined institution.

Pro Forma Merger Analysis. Sandler O'Neill analyzed certain potential pro forma
effects of the merger, based upon an exchange ratio of 1.185, Hudson River's and
Cohoes' current and projected income statements and balance sheets, and
assumptions regarding the economic environment, accounting and tax treatment of
the merger, charges associated with the merger, operating efficiencies and other
adjustments discussed with the senior managements of Hudson River and Cohoes. As
illustrated in the following table, this analysis indicated that the merger
would be accretive to Hudson River's projected earnings per share, and slightly
dilutive to tangible book value per share for the twelve months ended March 31,
2002. Also, it indicated the merger would enhance its tangible equity ratio. The
analysis indicated that the merger would be accretive to Cohoes' projected
earnings per share and slightly dilutive to tangible book value per share for
the twelve months ended March 31, 2002. The actual results achieved by Cohoes
and Hudson River may vary from projected results and the variations may be
material.

In connection with rendering its April 25, 2000 opinion, Sandler O'Neill
reviewed, among other things: (1) the merger agreement and exhibits thereto; (2)
the stock option agreements, dated April 25, 2000, by and between Hudson River
and Cohoes; (3) certain publicly available financial statements of Hudson River
and other historical financial information provided by Hudson River that they
deemed relevant; (4) certain publicly available financial statements of Cohoes
and other historical financial information provided by Cohoes that they deemed
relevant; (5) certain internal financial analyses and forecasts of Hudson River
prepared by and reviewed with management of Hudson River and the views of senior
management of Hudson River, based on certain limited discussions with certain
members of senior management, regarding Hudson River's past and current
business, financial condition, results of operations and future prospects; (6)
certain internal financial analyses and forecasts of Cohoes prepared by

                                       18

<PAGE>



and reviewed with management of Cohoes and the views of senior management of
Cohoes, based on certain limited discussions with certain members of senior
management, regarding Cohoes' past and current business, financial condition,
results of operations and future prospects; (7) the pro forma impact of the
merger; (8) the publicly reported historical price and trading activity for
Hudson River's and Cohoes' common stock, including a comparison of certain
financial and stock market information for Hudson River and Cohoes with similar
publicly available information for certain other companies the securities of
which are publicly traded; (9) the financial terms of recent business
combinations in the banking industry, to the extent publicly available; (10) the
current market environment generally and the banking environment in particular;
and (11) such other information, financial studies, analyses and investigations
and financial, economic and market criteria as they considered relevant.

In connection with rendering the Sandler Opinion, Sandler O'Neill confirmed the
appropriateness of its reliance on the analyses used to render its April 25,
2000 opinion by performing procedures to update certain of such analyses and by
reviewing the assumptions upon which such analyses were based and the other
factors considered in rendering its opinion.

In performing its reviews and analyses, Sandler O'Neill assumed and relied upon
the accuracy and completeness of all the financial information, analyses and
other information that was publicly available or otherwise furnished to,
reviewed by or discussed with it, and Sandler O'Neill did not assume any
responsibility or liability for independently verifying the accuracy or
completeness of any of such information. Sandler O'Neill did not make an
independent evaluation or appraisal of the assets, the collateral securing
assets or the liabilities, contingent or otherwise, of Hudson River or Cohoes or
any of their respective subsidiaries, or the collectibility of any such assets,
nor was it furnished with any such evaluations or appraisals. Sandler O'Neill is
not an expert in the evaluation of allowances for loan losses and it has not
made an independent evaluation of the adequacy of the allowance for loan losses
of Hudson River or Cohoes, nor has it reviewed any individual credit files
relating to Hudson River or Cohoes. With Hudson River's consent, Sandler O'Neill
has assumed that the respective allowances for loan losses for both Hudson River
and Cohoes are adequate to cover such losses and will be adequate on a pro forma
basis for the combined entity. In addition, Sandler O'Neill has not conducted
any physical inspection of the properties or facilities of Hudson River or
Cohoes. With respect to all financial projections reviewed with each company's
management and used by Sandler O'Neill in its analyses, Sandler O'Neill assumed
that they reflected the best currently available estimates and judgments of the
respective managements of the respective future financial performances of Hudson
River and Cohoes and that such performances will be achieved. Sandler O'Neill
expressed no opinion as to such financial projections or the assumptions on
which they were based.

Sandler O'Neill's opinion was necessarily based upon market, economic and other
conditions as they existed on, and could be evaluated as of, the date of its
opinion. Sandler O'Neill assumed, in all respects material to its analysis, that
all of the representations and warranties contained in the merger agreement and
all related agreements are true and correct, that each party to such agreements
will perform all of the covenants required to be performed by such party under
such agreements and that the conditions precedent in the merger agreement are
not waived. Sandler O'Neill also assumed, with Hudson River's consent, that
there has been no material change in Hudson River's and Cohoes' assets,
financial condition, results of operations, business or prospects since the date
of the last publicly filed financial statements available to them, that Hudson
River and Cohoes will remain as going concerns for all periods relevant to its
analyses, and that the merger will be accounted for as a purchase and will
qualify as a tax-free reorganization for federal income tax purposes.

Hudson River has agreed to pay Sandler O'Neill a transaction fee in connection
with the merger, a substantial portion of which is contingent upon the closing
of the merger. Hudson River will pay Sandler O'Neill a transaction fee of
approximately $250,000, of which approximately $50,000 has been paid and the
balance will be paid when the merger is closed. Hudson River has agreed to pay
Sandler O'Neill a fee of $150,000 for rendering its fairness opinion, which
shall be credited against any transaction fee that will become due and payable
upon closing. Hudson River has also agreed to indemnify Sandler O'Neill and its
affiliates and their respective partners, directors, officers, employees,
agents, and controlling persons against certain expenses and liabilities,
including liabilities under securities laws.

Sandler O'Neill has in the past provided certain other investment banking
services to Hudson River and has received compensation for such services. In
addition, Sandler O'Neill currently provides and may in the future provide
investment banking services to Hudson River and will receive compensation for
such services. In the ordinary

                                       19

<PAGE>



course of its business as a broker-dealer, Sandler O'Neill may also purchase
securities from and sell securities to Hudson River and Cohoes and may actively
trade the equity securities of Hudson River and Cohoes and their respective
affiliates for its own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.

Opinion of Cohoes' Financial Advisor

In April 2000, Keefe, Bruyette & Woods, Inc. was retained by Cohoes Bancorp,
Inc. to evaluate a potential strategic combination between Cohoes and Hudson
River Keefe, Bruyette & Woods, Inc., as part of its investment banking business,
is regularly engaged in the evaluation of business and securities in connection
with mergers and acquisitions, negotiated underwritings, and distributions of
listed and unlisted securities. Keefe, Bruyette & Woods, Inc. is familiar with
the market for common stocks of publicly traded banks, thrifts and bank and
thrift holding companies. The Cohoes board selected Keefe, Bruyette & Woods,
Inc. on the basis of the firm's reputation and its experience and expertise in
transactions similar to the merger and its prior work for and relationship with
Cohoes since the conversion of Cohoes Savings Bank from mutual to stock form in
1998.

Pursuant to its engagement, Keefe, Bruyette & Woods, Inc. was asked to render an
opinion as to the fairness, from a financial point of view, of the merger
consideration to shareholders of Cohoes. Keefe, Bruyette & Woods, Inc. delivered
its opinion to the Cohoes board that, as of April 25, 2000, the merger
consideration is fair, from a financial point of view, to the shareholders of
Cohoes. No limitations were imposed by the Cohoes Board upon Keefe, Bruyette &
Woods, Inc. with respect to the investigations made or procedures followed by it
in rendering its opinion. Keefe, Bruyette & Woods, Inc. has also delivered to
the Cohoes board of directors a written opinion dated the date of this proxy
statement/prospectus (the "KBW Opinion"), which is substantially identical to
its April 25, 2000 opinion. Keefe, Bruyette & Woods, Inc. has consented to the
inclusion herein of the summary of its opinion to the Cohoes Board and to its
entire opinion being attached hereto as Appendix C.

The full text of the opinion of Keefe, Bruyette & Woods, Inc., which is attached
as Appendix C to this proxy statement/prospectus, sets forth certain assumptions
made, matters considered and limitations on the review undertaken by Keefe,
Bruyette & Woods, Inc., and should be read in its entirety. The summary of the
opinion of Keefe, Bruyette & Woods, Inc. set forth in this proxy
statement/prospectus is qualified in its entirety by reference to the opinion.
Cohoes shareholders are urged to carefully read the KBW Opinion in connection
with their consideration of the proposed merger.

The KBW Opinion was directed to the Cohoes Board and was provided to Cohoes for
its information in considering the merger. The KBW Opinion is directed only to
the fairness of the exchange ratio to Cohoes shareholders from a financial point
of view. It does not address the underlying business decision of Cohoes to
engage in the merger or any other aspect of the merger and is not a
recommendation to any Cohoes shareholder as to how such shareholder should vote
at the Cohoes special meeting with respect to the merger or any other related
matter.

In rendering its opinion, Keefe, Bruyette & Woods, Inc. (1) reviewed the merger
agreement, (2) reviewed Cohoes' annual reports, proxy statements and Form 10-K's
since completing its initial public offering in December 1998 and Hudson River
annual reports, proxy statements and Form 10-K's since it completed its initial
public offering in July 1998 and certain other information considered relevant,
(3) discussed with senior management and the boards of directors of Cohoes and
its wholly-owned subsidiary, Cohoes Savings Bank, the current position and
prospective outlook for Cohoes to enhance future shareholder value, (4)
discussed with senior management of Hudson River their operations, financial
performance and future plans and prospects, (5) considered historical
quotations, levels of activity and prices of recorded transactions in Cohoes'
and Hudson River's common stock, (6) reviewed financial and stock market data of
other thrifts in a comparable asset range to Cohoes and Hudson River, (7)
reviewed certain recent business combinations of strategic alliance transactions
which Keefe, Bruyette & Woods, Inc. deemed comparable in whole or in part, and
(8) performed other analyses which Keefe, Bruyette & Woods, Inc. considered
appropriate.

In rendering its opinion, Keefe, Bruyette & Woods, Inc. assumed and relied upon
the accuracy and completeness of the financial information provided to it by
Cohoes and Hudson River. In its review, with the consent of the Cohoes. Board,
Keefe, Bruyette & Woods, Inc. did not undertake any independent verification of
the information provided

                                       20

to it, nor did it make any independent appraisal or evaluation of the assets or
liabilities, and potential or contingent liabilities of Cohoes or Hudson River.

The following is a summary of the material analyses performed by Keefe, Bruyette
& Woods, Inc., but is not a complete description of all the analyses underlying
Keefe, Bruyette & Woods, Inc.'s opinion. The preparation of a fairness opinion
is a complex process involving subjective judgments as to the most appropriate
and relevant methods of financial analysis and the application of those methods
to the particular circumstances. The process, therefore, is not necessarily
susceptible to a partial analysis or summary description. Keefe, Bruyette &
Woods, Inc. believes that its analyses must be considered as a whole and that
selecting portions of the factors and analyses considered without considering
all factors and analyses, or attempting to ascribe relative weights to some or
all such factors and analyses, could create an incomplete view of the evaluation
process underlying its opinion. Also, no company included in Keefe, Bruyette &
Woods, Inc.'s comparative analyses described below is identical to Cohoes or
Hudson River and no transaction is identical to the merger. Accordingly, an
analysis of comparable companies or transactions is not mathematical; rather, it
involves complex considerations and judgments concerning differences in
financial, market and operating characteristics of the companies and other
factors that could affect the public trading values or merger transaction
values, as the case may be, of Cohoes or Hudson River and the companies to which
they are being compared. . Keefe, Bruyette & Woods, Inc. presented the following
analyses:

Pro Forma Analysis of Affiliation. Keefe, Bruyette & Woods, Inc. analyzed
certain pro forma effects resulting from the strategic alliance. This analysis,
based upon historical annualized March 31, 2000 quarterly results and estimates
for the next three to five years for Cohoes and Hudson River based upon business
plan assumptions provided by management of each institution, projected an
earnings per share accretion of 16% for the twelve months ended March 31, 2002
for Cohoes. This assumes annual cost savings of $3.6 million (pre-tax). The
purpose of this analysis is to project the financial effects of the merger on
the balance sheet and income statement of Cohoes and the per share impact on the
stock of Cohoes. The outcome of this analysis, both independently as well as in
conjunction with other analyses, partially formulates the basis for Keefe,
Bruyette & Woods, Inc.'s opinion.

Regional Group Analysis. Keefe, Bruyette & Woods, Inc. reviewed the financial
performance of Cohoes based on various financial measures of asset size,
earnings performance, tangible equity/assets, market pricing ratios, market
capitalization, dividend-related ratios and deposit market share to all
publicly-traded thrift institutions headquartered in New York (25 in the group).
This analysis showed among other things, that as of March 31, 2000, Cohoes and
the combined company compared as follows:

Analysis of Selected Merger of Equals Transactions. Keefe, Bruyette & Woods,
Inc. analyzed 18 merger of equals transactions which occurred between thrift
institutions since 1995. Keefe, Bruyette & Woods, Inc. reviewed the terms of the
merger transactions with regard to the respective parties in each transaction
and the pro forma effect of each transaction. The merger of equals transactions
reviewed by Keefe, Bruyette & Woods, Inc. included the following: Golden State
Bancorp, Inc./First Nationwide Holdings, Dime Bancorp, Inc./Anchor Bancorp,
Inc., Charter One Financial, Inc./FirstFed Michigan Corporation, Associated
Banc-Corp/First Financial Corporation, Hudson Chartered Bancorp,
Inc./Progressive Bank, Inc., Pinnacle Financial Services/Indiana Federal
Corporation, Hinsdale Financial Corporation/Liberty Bancorp, Inc., Security
Capital Bancorp/Omni Capital Group, Coal City Corporation/Avondale Financial
Corp., Main Street Community Bancorp, Inc./Lexington Savings Bank, Fidelity
Financial of Ohio, Inc./Glenway Financial Corp., FCB Financial Corp./OSB

Improved Building & Loan Company.


                                       21

<PAGE>


Based on the above information Keefe, Bruyette & Woods, Inc. concluded that the
merger consideration was fair from a financial point of view relative to
comparable transactions. Further, the fairness analysis considered (1) the
relative market performance of the thrift stocks in general, especially small
cap stocks, over the past year; (2) the relative historical returns on equity of
Cohoes and Hudson River and (3) the expected performance of each company given
additional considerations such as the business plan, asset mix, net interest
margin, net interest spread and asset quality. The summary does not purport to
be a complete description of the analysis performed by Keefe, Bruyette & Woods,
Inc. and should not be construed independently of the other information
considered by Keefe, Bruyette & Woods, Inc. in rendering its opinion. Selecting
portions of Keefe, Bruyette & Woods, Inc.'s analysis or isolating certain
aspects of the comparable transactions, without considering all analysis and
factors, could create an incomplete or potentially misleading view of the
evaluation process.

In preparing its analysis, Keefe, Bruyette & Woods, Inc. made numerous
assumptions with respect to industry performance, business and economic
conditions and other matters, many of which are beyond the control of Keefe,
Bruyette & Woods, Inc., Cohoes and Hudson River. The analyses performed by
Keefe, Bruyette & Woods, Inc. are not necessarily indicative of actual values or
future results, which may be significantly more or less favorable than suggested
by such analyses and do not purport to be appraisals or reflect the prices at
which a business may be sold.

Keefe, Bruyette & Woods, Inc. will receive a fee of approximately $250,000 for
services rendered in connection with advising and issuing a fairness opinion
regarding the merger. As of the date of this proxy statement/prospectus, Keefe,
Bruyette & Woods, Inc. has received $100,000 of such fee, and the remainder of
the fee is due upon closing of the merger. In addition, Keefe, Bruyette & Woods,
Inc. has provided general merger and acquisition advisory services to Cohoes
since the completion of Cohoes' initial public offering in December 1998, for
which Keefe, Bruyette & Woods, Inc. will receive a $175,000 fee upon closing of
the merger.

Accounting and Tax Treatment

This summary of the federal income tax consequences of the merger may not
contain all the information that is important to you. It is not a complete
analysis or listing of all potential tax effects of the merger agreement; it
does not address tax consequences to persons subject to special treatment under
tax laws (such as dealers in securities, banks, insurance companies, tax-exempt
organizations, non-United States persons and shareholders who acquired their
shares as compensation); and it does not address the tax laws of any state,
local or foreign jurisdiction. It is based upon the Internal Revenue Code,
treasury regulations and administrative rulings and court decisions as of the
date of this document, all of which are subject to change. Cohoes shareholders
should consult their tax advisors as to the particular effect of their own
particular facts and circumstances on the federal income tax consequences of the
merger to them, and also as to the effect of any state, local, foreign and other
federal tax laws.

The merger will be treated as a purchase under generally accepted accounting
principles. Under current federal income tax law, based upon assumptions and
representations made by Hudson River and Cohoes, and assuming that the merger is
consummated in the manner set forth in the merger agreement, it is anticipated
that the following federal income tax consequences would result:

     o    the merger will qualify as a reorganization under Section 368(a) of
          the Internal Revenue Code;

     o    no gain or loss will be recognized by Hudson River or Cohoes as a
          result of the merger;

     o    no gain or loss will be recognized by any Cohoes shareholder upon the
          exchange of Cohoes common stock solely for Hudson River common stock
          in the merger;

     o    the aggregate tax basis of Hudson River common stock received will be
          the same as the basis of the Cohoes common stock surrendered in
          exchange (subject to any adjustments required as the result of receipt
          of cash in lieu of a fractional share interest in Hudson River common
          stock);

     o    the holding period of the shares of Hudson River common stock received
          will include the holding period of the Cohoes common stock surrendered
          in exchange, provided that the surrendered shares of Cohoes common
          stock were held as a capital asset at the time of the merger; and


                                       22

<PAGE>



     o    cash received in the merger in lieu of a fractional share interest
          will be treated as having been received as a distribution in full
          payment in exchange for the fractional share interest, and will
          qualify as capital gain or loss (assuming the Cohoes common stock
          surrendered in exchange was held as a capital asset by the shareholder
          at the time of the merger).

Each of Hudson River and Cohoes have received an opinion from its tax counsel
that the merger will have the anticipated tax consequences. Each counsel has
based its opinion upon representations made by Hudson River and Cohoes and upon
the assumption that the merger will be consummated in accordance with the terms
of the merger agreement. Both opinions are based entirely upon the Internal
Revenue Code, regulations then in effect or proposed under the Internal Revenue
Code, then current administrative rulings and practice and judicial authority,
all of which are subject to change, possibly with retroactive effect. It is a
condition to the merger agreement that each of Hudson River and Cohoes receive
an updated opinion from its tax counsel as of the effective time of the merger,
based upon the federal tax laws then in effect. You can find the details of the
tax opinion requirement in Section 7.1(f) of Appendix A.

No ruling has been or will be requested from the IRS. Unlike a ruling from the
IRS, the opinions of counsel are not binding on the IRS. There can be no
assurance that the IRS will not take a position contrary to the positions
reflected in such opinions or that such opinions would be upheld by the courts
if challenged.

Corporate Structure after the Merger

The merger will combine Hudson River and Cohoes into a single corporation under
the name "Cohoes-Hudson Bancorp, Inc." We also plan to merge Cohoes' savings
bank subsidiary into Hudson River's savings bank subsidiary.

Immediately after the merger, the combined corporation will have six pre-merger
Hudson River directors selected by the pre-merger Hudson River board and six
pre-merger Cohoes directors selected by the pre-merger Cohoes board. The merger
agreement also includes amendments to Hudson River's certificate of
incorporation designed to maintain this arrangement for six years, and
designates current officers of Hudson River and Cohoes as the initial officers
of the post-merger corporation. You can find the details of our plans for the
post-merger corporation in Section 2.2 of Appendix A. The amendments to Hudson
River's certificate of incorporation are discussed on page ___ and included as
Appendix D.

Regulatory Matters

Hudson River is subject to regulation and supervision by the Office of Thrift
Supervision as a savings and loan holding company. Hudson River Bank & Trust
Company and Cohoes Savings Bank are New York chartered savings banks regulated
by the New York State Banking Department and the Federal Deposit Insurance
Corporation. The merger of Cohoes with and into Hudson River must be approved by
the Office of Thrift Supervision and the New York State Banking Department. The
merger of Cohoes Savings Bank with and into Hudson River Bank & Trust Company
must be approved by the Federal Deposit Insurance Corporation and the New York
State Banking Department. In their reviews, the Office of Thrift Supervision,
the Federal Deposit Insurance Corporation and the New York State Banking
Department will evaluate, among other things, the financial and managerial
resources of the parties, the convenience and needs of the communities to be
served and the performance of the subsidiary banks under the Community
Reinvestment Act.

Federal law prohibits the approval of a merger if it would result in a monopoly
or be in furtherance of any combination or conspiracy to monopolize or to
attempt to monopolize the business of banking in any part of the United States,
or if its effect in any section of the country may be substantially to lessen
competition or to tend to create a monopoly, or if it would in any other manner
result in a restraint of trade, unless the anti-competitive effects of the
proposed merger are clearly outweighed in the public interest by the probable
effect of the transaction in meeting the convenience and needs of the
communities to be served.

The bank merger may not be consummated for a period of 30 days after receipt of
the final approval of the Federal Deposit Insurance Corporation, unless no
adverse comment has been received from the Department of Justice, in which case
the merger may be consummated on or after the 15th day after such final
approval.

                                       23

<PAGE>



The merger cannot proceed in the absence of the requisite regulatory approvals.
There can be no assurance that all regulatory approvals will be obtained or the
dates of those approvals. There can also be no assurance that regulatory
approvals received will not contain a condition or requirement that causes such
approvals to fail to satisfy the conditions set forth in the merger agreement.
See "The Merger Agreement -- What We Must Do to Complete the Merger."

Obligations of the Post-Merger Corporation

If the merger is completed:

     o    The post-merger corporation must indemnify former officers, directors
          and employees of the parties and their subsidiaries.

     o    The post-merger corporation must provide employment benefits to
          persons who were employees of Hudson River or Cohoes or their
          respective subsidiaries immediately prior to the merger.

You can find the details of these obligations in Sections 6.9 and 6.11 of
Appendix A.

What We Must Do to Complete the Merger

To complete the merger we must:

     o    Obtain approvals from the shareholders of both companies.

     o    Obtain regulatory approvals (without burdensome conditions) from each
          of the Office of Thrift Supervision, the Federal Deposit Insurance
          Corporation and the New York State Banking Department.

     o    Obtain federal and state authorization to issue shares in the merger.

     o    Obtain tax opinions from legal counsel.

     o    Obtain Nasdaq National Market approval to list the Hudson River shares
          to be issued in the merger.

     o    Avoid any material adverse effect on either of our companies.

     o    Avoid any breach of our representations and warranties.

     o    Fulfill our obligations under the merger agreement.

     o    Exchange customary documents at closing.

You can find details of the conditions to the merger in Article VII of Appendix
A. We cannot guarantee that all of these conditions will be satisfied or waived.

Amendments to Hudson River's Certificate of Incorporation

This summary may not include all of the information that is important to you.
You should read the complete text of the amendments to Hudson River's
certificate of incorporation which is included as Appendix D to this document.

Delaware law permits a plan of merger to include amendments to the certificate
of incorporation of the surviving corporation. We have included such amendments
in the merger agreement. If the merger is completed, these amendments will

Interests of Directors and Officers in the Merger that are Different from Your
Interests

     Employment Agreements. Hudson River and Hudson River Bank have entered into
employment agreements with Harry L. Robinson, Carl A. Florio, Richard A. Ahl,
Timothy E. Blow and Sidney D. Richter, which will become effective when the
merger becomes effective and will replace the present employment agreements of
these persons.

     Harry L. Robinson. Harry L. Robinson's employment agreement has a term of
six years which, until the third anniversary of the merger, will be extended
daily for one additional day, unless Cohoes-Hudson and Hudson River Bank give
notice to Mr. Robinson that the daily extensions will cease, or Mr. Robinson
gives a similar notice to Cohoes-Hudson and Hudson River Bank. Extensions of the
term also will cease automatically if Mr. Robinson's employment is terminated
for any reason. In addition, if by the sixth anniversary of the merger, no
change in control of Cohoes-Hudson or Hudson River Bank has occurred, Mr.
Robinson will retire as Chairman of the Board of Cohoes-Hudson, as Vice Chairman
of the Board of Hudson River Bank and as an officer or employee of Cohoes-Hudson
and Hudson River Bank and the term of his employment agreement will expire on
that date.

Mr. Robinson's employment agreement provides that he will serve as Chairman of
the Board of Directors of Cohoes-Hudson and as a Vice Chairman of the Board of
Directors of Hudson River Bank during the term of his employment agreement, and
will serve as the Chief Executive Officer of Cohoes-Hudson and Hudson River Bank
during the three years following the merger. In these positions, he will have
the authority and responsibilities prescribed by the By-laws of Cohoes-Hudson
and Hudson River Bank and that are customary for such positions. Beginning on
the third anniversary of the merger, the Boards of Directors of Cohoes-Hudson
and Hudson River Bank will have the right to elect Mr. Robinson as Co-Chief
Executive Officer and to elect an additional Co-Chief Executive Officer of
Cohoes-Hudson and Hudson River Bank. Six months after the third anniversary of
the merger, Mr. Robinson's right to serve as Chief Executive Officer or Co-Chief
Executive Officer will end but he will continue to serve as Chairman of the
Board of Directors of Cohoes-Hudson and as a Vice Chairman of the Board of
Directors of Hudson River Bank during the remaining term of his employment
agreement.

Mr. Robinson will receive an annual salary that is at least $460,000 and is
equal to the salary paid to the President of Cohoes-Hudson and Hudson River
Bank. Mr. Robinson will also be entitled to participate in benefit plans and
programs on the same terms as apply to the President of Cohoes-Hudson and Hudson
River Bank, including payment of country club dues and use of a company
automobile. In the event that, during the term of his employment agreement, Mr.
Robinson's employment is terminated by the Board of Directors of Cohoes-Hudson
or Hudson River Bank without cause, or Mr. Robinson resigns for any of the
reasons specified below, he will be entitled to receive as liquidated damages
continued group life, health and disability benefits and a cash lump sum payment
to compensate him for the loss of salary (on a present value basis), cash bonus
and incentive compensation and qualified and non-qualified retirement plan
benefits (on a present value basis) for not more than three years. In

                                       25

<PAGE>

addition, if Cohoes-Hudson elects to cause Mr. Robinson to surrender his
outstanding options and shares of restricted stock, Cohoes-Hudson will pay him
the value of his outstanding options and his shares of restricted stock, whether
vested or not.

The reasons specified in Mr. Robinson's employment agreement that would justify
his resigning and receiving the liquidated damages described above are a failure
to elect him to the positions in which he has a right to serve under his
employment agreement, a failure to vest in him the authority and
responsibilities associated with those positions, a failure to nominate or elect
him as a director of Cohoes-Hudson or Hudson River Bank, a change in his
principal place of employment to a location more than 25 miles from the
Cohoes-Hudson executive offices to be established in the vicinity of Albany, New
York, or the liquidation, dissolution, bankruptcy, or insolvency of
Cohoes-Hudson or Hudson River Bank.

If within one year before or at any time after a change in control of
Cohoes-Hudson or Hudson River Bank but prior to the sixth anniversary of the
merger, Mr. Robinson's employment with Cohoes-Hudson or Hudson River Bank is
terminated without cause or he resigns for one of the reasons specified above
that justifies his resigning and receiving the liquidated damages described
above, he will be entitled to receive, in addition to any liquidated damages, a
lump sum payment equal to the greater of (1) the salary and cash bonus or
incentive compensation he would have received if his employment had continued
until the sooner of the expiration of the term of his employment agreement or
the third anniversary of the termination of his employment or (2) 299% of his
average annual gross income from Cohoes-Hudson or its predecessor during the
past five full calendar years before the change in control. In the event that
due to a change in control, any amount paid or payable to Mr. Robinson is
subject to the 20% excise tax under Section 4999 of the Internal Revenue Code,
then he will be entitled to an additional payment such that on an after-tax
basis, he is indemnified for the excise tax.

Mr. Robinson's employment agreement contains a covenant not to compete, under
which he agrees that if his employment terminates before the expiration of the
term of his employment agreement, he will not compete with Cohoes-Hudson and
Hudson River Bank in any county in which either of them maintains an office
until the expiration of the sooner of two years from the date on which his
employment terminates or the date on which the term of his employment agreement
would otherwise expire. In addition, for two years after his employment
terminates, he will not solicit customers of Cohoes-Hudson or Hudson River Bank
or solicit employees of Cohoes-Hudson or its affiliates to accept other
employment in the counties where Cohoes-Hudson and Hudson River Bank maintain
offices.

     Carl A. Florio. Carl A. Florio's employment agreement has a term of six
years, beginning on the date of the merger, and the term is extended daily
thereafter unless Cohoes-Hudson and Hudson River Bank give notice to Mr. Florio
that the daily extensions will cease, or Mr. Florio gives a similar notice to
Cohoes-Hudson and Hudson River Bank. Extensions of the term also will cease
automatically if Mr. Florio's employment is terminated for any reason.

Mr. Florio's employment agreement provides that he will serve as a Vice Chairman
of the Board of Directors and as the President of Cohoes-Hudson and as a Vice
Chairman of the Board of Directors and as the President of Hudson River Bank
during the term of his employment agreement. As President, he will have the
authority and responsibilities prescribed by the By-laws of Cohoes-Hudson and
Hudson River Bank and that are customary for such positions. Beginning on the
third anniversary of the merger, the Boards of Directors of Cohoes-Hudson and
Hudson River Bank, to the extent permitted by their fiduciary duties, will elect
Mr. Florio as Co-Chief Executive Officer (and as President) if Mr. Robinson is
also serving as Co-Chief Executive Officer of Cohoes-Hudson and Hudson River
Bank. Upon the earlier of (a) six months after the third anniversary of the
merger or (b) the date that Mr. Robinson no longer serves as either the Chief
Executive Officer or Co-Chief Executive Officer of Cohoes-Hudson and Hudson
River Bank, the Boards of Directors of Cohoes-Hudson and Hudson River Bank, to
the extent permitted by their fiduciary duties, will elect Mr. Florio as sole
Chief Executive Officer and as President of Cohoes-Hudson and Hudson River Bank.
As sole Chief Executive Officer and President, he will have the authority and
responsibilities prescribed by the By-laws of Cohoes-Hudson and Hudson River
Bank and that are customary for such positions.

Mr. Florio will receive an annual salary that is at least $460,000 and is equal
to the salary paid to Mr. Robinson. Mr. Florio will also be entitled to
participate in benefit plans and programs of Cohoes-Hudson and Hudson River

                                       26

<PAGE>

Bank, including payment of country club dues and use of a company automobile. In
the event that, during the term of his employment agreement, Mr. Florio's
employment is terminated by the Board of Directors of Cohoes-Hudson or Hudson
River Bank without cause, or Mr. Florio resigns for any of the same reasons
specified in Mr. Robinson's employment agreement, he will be entitled to receive
the same liquidated damages as provided in Mr. Robinson's employment agreement,
except that if Mr. Florio resigns due to the failure of Hudson-Cohoes or Hudson
River Bank to elect him to the position of Co-Chief Executive Officer or Chief
Executive Officer, whichever is applicable, as provided above, then he will
receive liquidated damages of $3,000,000 in a lump sum payment instead of
receiving a lump sum payment of up to three years salary (on a present value
basis) and cash bonus or incentive compensation.

If within one year before or at any time after a change in control of
Cohoes-Hudson or Hudson River Bank during the term of his employment agreement,
Mr. Florio's employment with Cohoes-Hudson or Hudson River Bank is terminated
without cause or he resigns for one of the reasons that justifies his resigning
and receiving liquidated damages, he will be entitled to receive, in addition to
any liquidated damages, the same change in control lump sum payment and excise
tax indemnification payment as provided for in Mr. Robinson's employment
agreement.

Mr. Florio's employment agreement contains the same covenant not to compete and
agreement not to solicit employees and customers as provided for in Mr.
Robinson's agreement.

     Richard A. Ahl. Richard A. Ahl's employment agreement has a term of three
years, beginning on the date of the merger, and the term is extended daily
thereafter unless Cohoes-Hudson and Hudson River Bank give notice to Mr. Ahl
that the daily extensions will cease, or Mr. Ahl gives a similar notice to
Cohoes-Hudson and Hudson River Bank. Extensions of the term also will cease
automatically if Mr. Ahl's employment is terminated for any reason.

Mr. Ahl's employment agreement provides that he will serve as the Chief
Operating Officer and Executive Vice President of Cohoes-Hudson and of Hudson
River Bank during the term of his employment agreement. Mr. Ahl will receive an
annual salary that is at least $230,000. Mr. Ahl will also be entitled to
participate in benefit plans and programs of Cohoes-Hudson and Hudson River
Bank. In the event that, during the term of his employment agreement, Mr. Ahl's
employment is terminated by the Board of Directors of Cohoes-Hudson or Hudson
River Bank without cause, or Mr. Ahl resigns for any of the same reasons
specified in Mr. Robinson's employment agreement that are applicable to him, he
will be entitled to receive the same type of liquidated damages as provided for
in Mr. Robinson's employment agreement.

If in connection with or within 18 months after a change in control of
Cohoes-Hudson or Hudson River Bank during the term of his employment agreement,
Mr. Ahl's employment with Cohoes-Hudson or Hudson River Bank is terminated
without cause or he resigns for one of the reasons that justifies his resigning
and receiving liquidated damages, he will be entitled to receive, in addition to
any liquidated damages, a lump sum payment equal to the greater of (1) the
salary and cash bonus or incentive compensation he would have received if his
employment had continued until the expiration of the term of his employment
agreement or (2) 299% of his average annual gross income from Cohoes-Hudson or
its predecessor during the past five full calendar years before the change in
control. He will also be entitled to receive an excise tax indemnification
payment as provided for in Mr. Robinson's employment agreement.

Mr. Ahl's employment agreement contains the same covenant not to compete and
agreement not to solicit employees and customers as provided for in Mr.
Robinson's agreement.

     Sidney D. Richter. Sidney D. Richter's employment agreement is the same as
Mr. Ahl's employment agreement, except that (a) he will serve as Executive Vice
President of Cohoes-Hudson and as Executive Vice President and the Senior Loan
Officer of Hudson River Bank, (b) his annual salary will be at least $160,000
and (c) he will be entitled to resign and receive liquidated damages if his
principal place of employment is changed to a location more than 25 miles from
the main office of Hudson River Bank (as opposed to the executive offices of
Hudson-Cohoes in the Albany, New York vicinity).

     Timothy E. Blow. Timothy E. Blow's employment agreement is the same as Mr.
Ahl's employment agreement, except that (a) he will serve as the Chief Financial
Officer of Cohoes-Hudson and of Hudson River

                                       27

<PAGE>

Bank, (b) his annual salary will be at least $150,000, (c) the term of his
employment is two years (rather than three years), subject to daily extension,
and (d) his lump sum payment upon termination of his employment in connection
with or within 18 months after a change in control will be equal to the greater
of (1) the salary and cash bonus or incentive compensation he would have
received if his employment had continued until the expiration of the term of his
employment agreement or (2) 200% of his average annual gross income from
Cohoes-Hudson or its predecessor during the past five full calendar years before
the change in control.

     Director Emeritus Plan. Prior to the consummation of the merger, Hudson
River will adopt a Director Emeritus Plan. Each director of Cohoes, Hudson
River, Cohoes Savings Bank and Hudson River Bank (and the sole director emeritus
of Cohoes and each director emeritus of Hudson River selected by its Board of
Directors) who does not become a director of Cohoes-Hudson or Hudson River Bank
upon consummation of the merger or the bank merger will be entitled to become a
director emeritus of Cohoes-Hudson under the plan. The term of each director
emeritus will be six years, or three years if his or her prior service with
Cohoes, Hudson River, Cohoes Savings Bank or Hudson River Bank was less than
three years. Each director emeritus will receive an annual retainer of $31,500,
and, subject to change by the Board of Directors of Cohoes-Hudson, will be
entitled to attend regular meetings of the Board. If a director emeritus dies
during his or her term, the retainer will be paid to his or her beneficiary or
estate. If Carl A. Florio or Harry L. Robinson ceases to be a director of both
Cohoes-Hudson and Hudson River Bank before all shares of restricted stock
granted to him by Hudson River or Cohoes, whichever the case may be, prior to
the merger have vested, he will be entitled to become a director emeritus and
receive the annual retainer under the plan until all such shares have vested or
have been acquired by Cohoes-Hudson under his employment agreement. In addition,
if Harry L. Robinson ceases to be a director of both Cohoes-Hudson and Hudson
River Bank before all shares of restricted stock granted to him by Cohoes-Hudson
at the effective time of the merger have vested, he will be entitled to become a
director emeritus and receive the annual retainer under the plan until all such
shares have vested or have been acquired by Cohoes-Hudson under his employment
agreement, unless his employment is terminated for cause or he voluntarily
terminates his employment without good reason during the six years following the
merger or resigns as a director.

     Stock Options. On the date the merger is consummated, Cohoes-Hudson will
grant:

          o   to each person other than Harry L. Robinson who is a director or
          director emeritus of Cohoes immediately before the merger, an option
          to acquire 7,490 shares of common stock of Cohoes-Hudson at an
          exercise price equal to the greater of $16.44 per share or the market
          value of such stock on the date the option is granted,

          o   to Harry L. Robinson an option to acquire 45,816 shares of common
          stock of Cohoes-Hudson at an exercise price equal to the greater of
          $19.19 per share or the market value of such stock on the date the
          option is granted, and

          o   to Richard A. Ahl an option to acquire 16,660 shares of common
          stock of Cohoes-Hudson at an exercise price equal to the greater of
          $22.07 per share or the market value of such stock on the date the
          option is granted.

Each option will vest in four equal installments on January 5, 2001, 2002, 2003
and 2004 in accordance with Hudson's present option plan, and will expire on
January 5, 2009.

     Restricted Stock. On the date the merger is consummated, Cohoes-Hudson will
grant shares of restricted stock as follows:

          o    to each director of Cohoes (other than Harry L. Robinson) and to
               the sole emeritus director of Cohoes, 9,083 shares,

          o    to Harry L. Robinson, 71,888 shares, and

          o    to Richard A. Ahl, 32,373 shares.


                                       28

<PAGE>

For each person who serves as a director emeritus of Cohoes-Hudson, such shares
of Cohoes-Hudson restricted stock will vest in equal (or substantially equal)
annual installments during the six years following the merger. For all other
persons, the shares of Cohoes-Hudson restricted stock will vest in nine equal
(or substantially equal) annual installments commencing January 5, 2001. As a
condition to the granting of shares of Cohoes-Hudson restricted stock as
described above to Harry L. Robinson, Richard A. Ahl and to each person who will
serve as a director of Cohoes-Hudson or Hudson River Bank, such person must
enter into an agreement to modify the vesting schedule of his or her existing
Cohoes restricted stock to conform to the nine year vesting schedule for the
shares of Cohoes-Hudson restricted stock described above.

Other Provisions of the Merger Agreement

Although the completion of the merger requires shareholder approval, many
provisions of the merger agreement became effective immediately upon its
signing. Your vote was not required to make these provisions binding obligations
of Hudson River and Cohoes.

     Representations and Warranties. Each party has made representations and
warranties to the other party with respect to various matters, including its
financial statements, capital structure, business, loans, investments,
regulatory filings and benefit plans. These representations and warranties must
be true and correct upon both signing of the merger agreement and the completion
of the merger. A party can terminate the merger agreement if the other party's
representations and warranties are not true and correct because of a material
adverse effect on that other party. If the merger is completed, or if the merger
agreement is terminated for some unrelated reason, the representations and
warranties become void. You can find details of these obligations in Articles
III, IV and V of Appendix A.

     Cooperation and Conduct of Business. Each party has agreed to cooperate in
completing the merger and to avoid extraordinary transactions between the
signing of the merger agreement and the completion of the merger. These
provisions become void if the merger is completed. These provisions also become
void if the merger agreement is terminated, except for those related to
confidentiality, joint press releases and shared expenses. You can find details
of these obligations in Article VI of Appendix A.

     Waiver and Amendment. Section 8.4 of Appendix A allows either party to
extend the time for the performance of any obligation by the other party, and to
waive (to the extent permitted by law) any condition or obligation of the other
party. Section 8.5 allows the boards of the parties to amend the merger
agreement without shareholder vote so long as the merger consideration is not
changed and the effect on the shareholders is not materially adverse.

     Termination. The merger agreement may be terminated by mutual agreement of
the parties (even after shareholder approval), or by a non-breaching party under
any of the following circumstances:

     o    In response to a material breach which is not cured within 30 days.

     o    If any required regulatory or shareholder approval is denied.

     o    If the merger is not completed by February 28, 2001.

     You can find details of the termination provisions in Sections 8.1, 8.2 and
8.3 to Appendix A.

The Stock Option Agreements

To increase the likelihood that the merger will be completed, and to discourage
other persons who may be interested in combining with either party, each of
Hudson River and Cohoes has granted the other a conditioned option to purchase
up to 19.9% of the outstanding shares of its common stock at a fixed price equal
to the closing sales price of the common stock of the respective parties on
April 24, 2000. These options are intended to make it more likely that the
merger will be completed on the agreed terms and to compensate a party for its
efforts and costs in case the merger is not completed due to a third party
proposal for a business combination with the other party. The options may
therefore discourage proposals for alternative business combinations, even if a
third party were prepared to

                                       29

<PAGE>

offer Hudson River or Cohoes more favorable terms. Copies of the Stock Option
Agreements are attached to this document as Appendices D and E. These agreements
become void if the merger is completed.

Exchange of Certificates

We will appoint an exchange agent to handle the exchange of Cohoes stock
certificates for Hudson River stock certificates and the payment of cash for any
fractional share. Promptly after the merger is completed, the exchange agent
will send to each holder of Cohoes common stock a letter of transmittal for use
in the exchange and instructions explaining how to surrender Cohoes certificates
to the exchange agent. Holders of Cohoes common stock that surrender their
certificates to the exchange agent, together with a properly completed letter of
transmittal, will receive the appropriate merger consideration. Holders of
unexchanged shares of Cohoes common stock will not be entitled to receive any
dividends or other distributions payable by Hudson River after the effective
time until their certificates are surrendered. However, when those certificates
are surrendered for shares of Hudson River common stock, any unpaid dividends or
distributions will be paid, without interest.

Cohoes common stock certificates should not be returned with the enclosed proxy
and should not be forwarded to the exchange agent until you receive the
transmittal form.

Resales of Hudson River Common Stock by Affiliates of Cohoes

The shares of Hudson River common stock to be issued in the merger will be
registered under the Securities Act and will be freely transferable under the
Securities Act, except for shares issued to any shareholder who may be deemed to
be an "affiliate" of Cohoes for purposes of Rule 145 under the Securities Act as
of the date of the Cohoes special meeting. Affiliates of Cohoes may not sell
their shares of Hudson River common stock acquired in the merger except pursuant
to an effective registration statement under the Securities Act covering those
shares or in compliance with Rule 145 or another applicable exemption from the
registration requirements of the Securities Act. Persons who may be deemed to be
affiliates of Cohoes generally include individuals or entities that control, are
controlled by or are under common control with Cohoes, and may include certain
officers and directors of Cohoes as well as certain principal shareholders of
Cohoes.

Dissenters' Rights

Delaware law does not grant dissenters' rights to the shareholders of either
company.

The timing and amount of future dividends will depend upon earnings, cash
requirements, the financial condition of Hudson River and its subsidiaries,
applicable government regulations and other factors the Hudson River board
considers relevant. The dividend policies on the Hudson River common stock are
subject to the discretion of the Hudson River board of directors. The merger
agreement provides that the initial dividend on the Cohoes-Hudson Bancorp, Inc.
common stock will be $0.06 per share for the first full quarterly dividend
following completion of the merger, and that neither party will increase their
regular quarterly cash dividends prior to completion of the merger without the
other party's consent.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements (pro
forma financial statements) are based on the historical financial statements of
Hudson River and Cohoes and have been prepared to illustrate the effect of the
merger. Consummation of the merger is subject to a number of conditions, and no
assurance can be given that the merger will be consummated on the currently
anticipated terms, or at all.

The following unaudited pro forma condensed combined balance sheet as of March
31, 2000 is based on the unaudited historical consolidated balance sheets of
Hudson River and Cohoes at that date, assuming that the merger had been
consummated on March 31, 2000 and accounted for using the purchase method of
accounting.

The unaudited pro forma condensed combined income statement reflects the
combination of the historical results of operations of Hudson River for the
fiscal year ended March 31, 2000, and of Cohoes for the twelve months ended
March 31, 2000.

The unaudited pro forma condensed combined income statement gives effect to the
merger using the purchase method of accounting and assume that (1) the merger

These pro forma financial statements should be read in conjunction with the
historical financial statements and related notes of Hudson River and Cohoes
incorporated by reference in this joint proxy statement/prospectus.

As noted above, the merger will be accounted for using the purchase method of
accounting. Accordingly, the pro forma adjustments made for the purpose of
preparing the pro forma financial statements are based upon certain assumptions
and estimates regarding the amount of negative goodwill (which represents the
excess of the fair value of the net assets acquired over the total acquisition
cost) which will arise from the merger and the period over which such negative
goodwill will be accreted. The actual negative goodwill arising from the merger
will be based on the excess of the fair value of the net assets acquired over
the total acquisition cost, based on fair value estimates and other information
determined as of the date the merger is consummated. For purposes of the pro
forma financial statements, the fair value of Cohoes' assets and liabilities was
estimated based upon information available as of March 31, 2000. The actual fair
value adjustments to the assets and liabilities of Cohoes will be made on the
basis of appraisals and evaluations that will be made as of the date the merger
is consummated and may, therefore, differ significantly from those reflected in
these pro forma financial statements. In the opinion of Hudson's management, the
estimates used in the preparation of these pro forma financial statements are
reasonable under the circumstances.

The combined company expects to achieve benefits from the merger including
operating cost savings and revenue enhancements. The pro forma earnings set
forth in this section do not reflect any potential cost savings or revenue
enhancements which are expected to result from the combination of operations of
Hudson River and Cohoes and, accordingly, may not be indicative of the results
of future operations. No assurances can be given with respect to the ultimate
level of cost savings or revenue enhancements to be realized. As a result, the
unaudited pro forma condensed combined income statement is not necessarily
indicative of either the results of operations that would have occurred had the
merger been effective at the beginning of the respective periods or of future
results of the combined company. In addition, the consummation of the merger is
subject to satisfaction of a number of conditions, and no assurance can be given
that the merger will be consummated on the currently anticipated terms, or at
all.

1.   Represents the reclassification of Cohoes' securities held to maturity
     portfolio as securities available for sale, at estimated fair value. The
     securities are assumed to have a weighted-average life of 5 years and the
     fair value adjustment (discount) is accreted on a straight line basis over
     this time period into interest on securities available for sale.

2.   Represents the estimated fair value adjustment relating to Cohoes' loan
     portfolio. The estimated life of this portfolio is assumed to be 7 years.
     The adjustment is assumed to accrete on a straight line basis over this
     time period into interest and fees on loans.

3.   Negative goodwill generated by the excess of the fair value of the net
     assets acquired over the cost of the acquired institution is allocated to
     all noncurrent, nonmonetary assets of Cohoes. Premises and equipment and
     goodwill and other intangibles of Cohoes are the only noncurrent,
     nonmonetary assets identified and the values are reduced accordingly. The
     adjustments to estimate the amount of negative goodwill used in the
     preparation of the unaudited pro forma condensed combined balance sheet are
     summarized below (dollars in thousands, except per share data):

         Premises & equipment                                   $         7,725
         Goodwill and other intangibles                         $         1,747
Estimated tax effect of fair value adjustments and allocations  $        (6,365)
                                                                ---------------
Estimated negative goodwill                                     $       (19,882)

     The estimated negative goodwill is assumed to be accreted into income over
     a period of 10 years, the estimated period of benefit. The accretion of the
     negative goodwill is not taxable.

4.   Represents the estimated income tax effects of the estimated purchase
     accounting adjustments at an assumed marginal tax rate of 40%. The tax
     expense or benefit is reflected in the pro forma income statement during
     the period that the related purchase accounting adjustments are assumed to
     be accreted or amortized, respectively.

5.   Represents the estimated fair value adjustment relating to Cohoes' time
     deposits. The weighted average remaining maturity of these time deposits is
     assumed to be 12 months. The adjustment is assumed to accrete on a straight
     line basis over this time period as a reduction of interest expense on
     deposits.

6.   Represents the estimated fair value adjustment relating to Cohoes'
     long-term borrowings. The weighted average remaining maturity of these
     borrowings is assumed to be 7 years. The adjustment is assumed to amortize
     on a straight line basis over this time period as an increase to interest
     expense on long-term borrowings.

7.   Represents an estimated liability related to the settlement of certain
     employment agreements, investment banking, legal and accounting fees, and
     severance benefits in conjunction with the closing of the transaction.

8.   Represents the elimination of Cohoes' equity as of the date of the
     transaction, offset by the issuance of 9,376,022 shares of Hudson River
     common stock at an average market price of $9.52. The average market price
     was obtained by averaging the closing market price of Hudson River common
     stock before, after and including the date of the announcement. Amount also
     includes the estimated fair value of Hudson River stock options exchanged
     for outstanding Cohoes stock options valued as of the date of the
     announcement using the Black-Scholls option pricing model, as well as the
     effect of the exchange of Cohoes unvested restricted stock for Hudson River
     unvested restricted stock.

9.   Represents the amount of expense recorded by Cohoes during the 12 months
     ended March 31, 2000 relating to depreciation on buildings and equipment
     and the amortization of goodwill and other intangibles. These amounts are
     eliminated from the pro forma income statement as the negative goodwill
     generated from the transaction has been allocated to eliminate Cohoes'
     premises and equipment and goodwill and other intangibles.

10.  Basic earnings per share is calculated utilizing Hudson River's
     weighted-average shares outstanding for the year ended March 31, 2000 of
     14,556,648 combined with the shares issued for Cohoes common shares
     outstanding of 9,376,022, less 408,792 shares of unvested restricted stock
     exchanged in the transaction. Diluted earnings per share is calculated
     utilizing Hudson River's weighted-average shares giving effect to potential
     common shares outstanding for the year ended March 31, 2000 of 14,577,742
     combined with the shares issued for Cohoes common shares outstanding of
     9,376,022, less 408,792 shares of unvested restricted stock exchanged in
     the transaction.

     AMENDMENTS TO THE HUDSON RIVER 1998 STOCK OPTION AND INCENTIVE PLAN AND
              THE HUDSON RIVER 1998 RECOGNITION AND RETENTION PLAN

Hudson River shareholders are being asked to approve increases in the number of
shares available under (a) Hudson River's 1998 Stock Option and Incentive Plan
from 1,785,375 to 1,930,241, and (b) Hudson River's 1998 Recognition and
Retention Plan (RRP) from 714,150 to 918,324. All other features of the two
plans will remain the same, and the plans are described below.

The Hudson River board is recommending these increases in the number of shares
because Hudson River has agreed to grant additional options and awards to
certain executive officers and directors of Cohoes under the merger agreement.
See "The Merger - Interests of Directors and Officers in the Merger that are
Different from Your Interests" for a discussion of who will receive the awards
and the amount of the awards.

The Hudson River board unanimously recommends that Hudson shareholders vote
"FOR" the amendment of these two plans.

Description of the 1998 Stock Option and Incentive Plan

This summary of the 1998 Stock Option and Incentive Plan may not contain all the
information that is important to you. You should read the full text of the plan
which is attached as Appendix G. This summary is qualified in its entirety by
reference to the plan.

     Principal Features of the Stock Option Plan. The Stock Option Plan provides
for awards in the form of stock options, stock appreciation rights and limited
stock appreciation rights. Each award shall be on such terms and conditions,
consistent with the Stock Option Plan and applicable New York State Banking
Board and FDIC regulations, as the committee administering the Stock Option Plan
may determine. Subject to certain exceptions described herein, awards made under
such plan generally vest at a rate of no quicker than one-fifth of the initial
award per year, subject to the participant maintaining continuous service with
Hudson River or its subsidiaries from the date of grant.

Shares awarded pursuant to the Stock Option Plan may be either authorized but
unissued shares or reacquired shares held by Hudson River in its treasury. Any
shares subject to an award which expires or is terminated unexercised will again
be available for issuance under the Stock Option Plan or any other plan of
Hudson River or its subsidiaries. Generally, no award or any right or interest
therein is assignable or transferable except under certain limited exceptions
set forth in the Stock Option Plan.

The Stock Option Plan is administered by the Compensation Committee of the board
of Hudson River. Pursuant to the terms of the Stock Option Plan, any director,
officer or employee of Hudson River or its affiliates is eligible to participate
in the Stock Option Plan. Accordingly, there are currently 338 persons eligible
to participate in the Plan. In granting awards under the Stock Option Plan, the
Compensation Committee considers, among other things, position and years of
service, value of the participant's services to Hudson River and the bank and
the added responsibilities of such individuals as employees, directors and
officers of a public company.

     Stock Options. Under the terms of the Stock Option Plan, the Compensation
Committee may grant either "incentive stock options" as defined under Section
422 of the Internal Revenue Code or stock options not intended to qualify as
such ("non-qualified stock options").

In general, stock options will not be exercisable after the expiration of their
terms. The term of stock options may not exceed ten years from the date of
grant. Unless otherwise determined by the Compensation Committee, in the event a
participant ceases to maintain continuous service (as defined in the Stock
Option Plan) with Hudson River or one of its affiliates, for any reason
(excluding death, disability and termination for cause), an exercisable stock
option will continue to be exercisable for three months thereafter but in no
event after the expiration date of the option. Unless otherwise provided by the
Compensation Committee, in the event that continuous service terminates as a
result of the disability of a participant, all options not then exercisable
shall become exercisable in full and remain exercisable for a period of one year
from the date of such disability. Unless otherwise provided by the Compensation
Committee, in the event of death of a participant, all options not then
exercisable shall become exercisable in full. Unless otherwise provided by the
Compensation Committee, in the event of the death of a participant during such
service or within the three-month period described above following termination
of service described above, an exercisable option will continue to be
exercisable for one year, to the extent exercisable by the participant upon his
death, but in no event later than ten years after grant. Following the death of
any participant, the Compensation Committee may, as an alternative means of
settlement of an option, elect to pay to the holder thereof an amount of cash
equal to the amount by which the market value of the shares covered by the
option on the date of exercise exceeds the exercise price. A stock option will
automatically terminate and will no longer be exercisable as of the date a
participant is notified of termination for cause.

The exercise price for the purchase of shares subject to a stock option at the
date of grant may not be less than 100% of the market value of the shares
covered by the option on that date. The exercise price must be paid in full in
cash or, if permitted by the Compensation Committee, shares of common stock, or
a combination of both.

     Stock Appreciation Rights (SARs). The Compensation Committee may grant SARs
at any time, whether or not the participant then holds stock options, granting
the right to receive the excess of the market value of the shares represented by
the SARs on the date exercised over the exercise price. SARs generally will be
subject to the

                                       38

<PAGE>



same terms and conditions and exercisable to the same extent as stock options,
as described above. Upon the exercise of a SAR, the participant will receive the
amount due in cash or shares, or a combination of both, as determined by the
Compensation Committee. SARs may be related to stock options, in which case the
exercise of one will reduce to that extent the number of shares represented by
the other.

SARs will require an expense accrual by Hudson River each year for the
appreciation on the SARs which it is anticipated will be exercised. The amount
of the accrual is dependent upon whether and the extent to which the SARs are
granted and the amount, if any, by which the market value of the SARs exceeds
the exercise price.

     Limited Stock Appreciation Rights. Limited SARs will be exercisable only
for a limited period in the event of a tender or exchange offer for shares of
Hudson River's common stock, other than by Hudson River, where 25% or more of
the outstanding shares are acquired in that offer or any other offer which
expires within 60 days of that offer. The amount paid on exercise of a limited
SAR will be the excess of (a) the market value of the shares on the date of
exercise, or (b) the highest price paid pursuant to the offer, over the exercise
price. Payment upon exercise of a limited SAR will be in cash.

Limited SARs may be granted at the time of, and must be related to, the grant of
a stock option or SAR. The exercise of one will reduce to that extent the number
of shares represented by the other. Subject to vesting requirements contained in
New York State Banking Board and FDIC regulations, limited SARs will be
exercisable only for the 45 days following the expiration of the tender or
exchange offer, during which period the related stock option or SAR will be
exercisable. However, no limited SAR will be exercisable by a director, senior
officer or ten percent beneficial owner of Hudson River within six months of the
date of its grant.

     Effect of Merger and Other Adjustments. Shares as to which awards may be
granted under the Stock Option Plan, and shares then subject to awards, will be
adjusted appropriately by the Compensation Committee in the event of any merger,
consolidation, reorganization, recapitalization (including a return of capital,
whether non-taxable or otherwise), combination or exchange of shares, stock
dividend, stock split or other change in the corporate structure or common stock
of Hudson River.

In the event of any merger, consolidation or combination of Hudson River with or
into another company or other entity, whereby either Hudson River is not the
continuing entity or its outstanding shares of common stock are converted into
or exchanged for different securities, cash or property, or any combination
thereof, pursuant to a plan or agreement the terms of which are binding upon all
shareholders, any participant to whom a stock option or SAR has been granted at
least six months prior to such event will have the right upon exercise of the
option or SAR (subject to the terms of the Stock Option Plan and any other
limitation or vesting period applicable to such option or SAR) to an amount
equal to the excess of fair market value on the date of exercise of the
consideration receivable in the merger, consolidation or combination with
respect to the shares covered or represented by the stock option or SAR over the
exercise price of the option or SAR multiplied by the number of shares with
respect to which the option or SAR has been exercised.

     Amendment and Termination. The board of Hudson River may at any time amend,
suspend or terminate the Stock Option Plan or any portion thereof, subject to
compliance with New York State Banking Board and FDIC regulations, but may not,
without the prior ratification of the shareholders, make any amendment which
shall (1) increase the aggregate number of securities which may be issued under
the Stock Option Plan (except as specifically set forth under the Stock Option
Plan), (2) materially change the requirements as to eligibility for
participation in the Stock Option Plan or (3) change the class of persons
eligible to participate in the Stock Option Plan, provided, however, that no
such amendment, suspension or termination shall impair the rights of any
participant, without his consent, in any award made pursuant to the Stock Option
Plan. Unless previously terminated, the Stock Option Plan shall continue in
effect for a term of ten years, after which no further awards may be granted
under the Stock Option Plan.

     Federal Income Tax Consequences. Under present federal income tax laws,
awards under the Stock Option Plan will have the following consequences:

(1)  The grant of an award, by itself, will generally neither result in the
     recognition of taxable income to the participant nor entitle Hudson River
     to a deduction at the time of such grant.

                                       39

<PAGE>



(2)  In order to qualify as an incentive stock option, a stock option awarded
     under the Stock Option Plan must meet the conditions contained in Section
     422 of the Internal Revenue Code, including the requirement that the shares
     acquired upon the exercise of the stock option be held for at least one
     year after the date of exercise and at least two years after the grant of
     the option. The exercise of an incentive stock option will generally not,
     by itself, result in the recognition of taxable income to the participant
     nor entitle Hudson River to a deduction at the time of such exercise.
     However, the difference between the exercise price and the fair market
     value of the option shares on the date of exercise is an item of adjustment
     which may, in certain situations, trigger the alternative minimum tax. The
     alternative minimum tax is incurred only when it exceeds the regular income
     tax.

(3)  If the shares are held by the participant for at least one year after the
     incentive stock option is exercised and two years after the incentive stock
     option was granted, the participant will recognize a long-term capital gain
     or loss upon disposition of the shares and Hudson River will not be
     entitled to a corresponding deduction. The capital gain will be considered
     long-term if the shares are held for more than 12 months. The amount of
     such gain or loss will be equal to the difference between the amount
     realized by the participant upon disposition of the shares and the amount
     paid by the participant for such shares.

(4)  If the shares acquired upon exercise of an incentive stock option are not
     held for at least one year after transfer of such shares to the participant
     and two years after the grant of the incentive stock option, the
     participant generally will recognize ordinary income or loss upon
     disposition of the shares in an amount equal to the difference between the
     exercise price and the fair market value of the shares on the date of
     exercise. In such an event, Hudson River will generally be entitled to a
     corresponding deduction, provided Hudson River meets its federal tax
     reporting obligations. The participant will also recognize capital gain or
     loss equal to the difference, if any, between the sale price and the fair
     market value of the shares on the date of exercise of the incentive stock
     option; such capital gain or loss will be characterized as short- or
     long-term depending on how long the shares are held after the date of
     exercise of the incentive stock option. Hudson River will not be entitled
     to a corresponding deduction for such capital gain or loss.

(5)  The exercise of a non-qualified stock option will result in the recognition
     of ordinary income by the participant on the date of exercise in an amount
     equal to the difference between the exercise price and the fair market
     value on the date of exercise of the shares acquired pursuant to the stock
     option. Hudson River will be allowed a deduction at the time and in the
     amount of any ordinary income recognized by the participant upon the
     exercise of a non-qualified stock option, provided Hudson River meets its
     federal tax reporting obligations. Upon sale of the shares acquired upon
     exercise of a non-qualified stock option, any appreciation or depreciation
     in the value of such shares from the time of exercise will result in the
     recognition of a capital gain or loss by the participant. Such gain or loss
     will be short- or long-term capital gain or loss depending upon how long
     the participant held the shares following exercise of the non-qualified
     stock option.

(6)  The exercise of an SAR will result in the recognition of ordinary income by
     the participant on the date of exercise in an amount of cash, and/or the
     fair market value on that date of the shares, acquired pursuant to the
     exercise. Hudson River will be entitled to a corresponding deduction
     provided that it meets its federal tax reporting obligations.

Description of the 1998 Recognition and Retention Plan

This summary of the 1998 Recognition and Retention Plan may not contain all the
information that is important to you. You should read the full text of the plan
which is attached as Appendix H. This summary is qualified in its entirety by
reference to the plan.

     Principal Features of the RRP. The RRP provides for the award of shares of
common stock, at no cost to the recipient, subject to the restrictions described
below. Each award under the RRP is made on such terms and conditions, consistent
with the terms of the RRP and applicable New York State Banking Board and FDIC
regulations, as the Compensation Committee shall determine.

The RRP is administered by Hudson River's Compensation Committee. The
Compensation Committee will select the recipients and terms of awards pursuant
to the RRP. In determining to whom and in what amount to grant

                                       40

<PAGE>


awards, the Compensation Committee considers the position and responsibilities
of eligible individuals, the value of their services to Hudson River and the
bank and other factors it deems relevant. Pursuant to the terms of the RRP, any
director, officer or employee of Hudson River or its affiliates may be selected
by the Compensation Committee to participate in the RRP. As of the date hereof,
there are approximately 338 persons eligible to participate in the RRP.

The RRP provides that shares used to fund awards under the RRP may be either
authorized but unissued shares or reacquired shares held by Hudson River in its
treasury. Any RRP shares which are forfeited will again be available for
issuance under the RRP.

Holders of RRP shares may not sell, assign, transfer, pledge, vote or otherwise
encumber any of those shares during the restricted period. All shares subject to
restriction will be voted by a designated trustee. All dividends paid on RRP
shares still subject to restrictions will be deferred and held for the account
of the participant thereof until the earlier of the lapse of the restrictions on
such shares or the death or disability of the participant.

     Adjustments Upon Changes in Capitalization. Shares awarded under the RRP
will be adjusted by the Compensation Committee in the event of a reorganization,
recapitalization, stock split, stock dividend, combination or exchange of
shares, merger, consolidation or other change in corporate structure or the
common stock of Hudson River.

     Federal Income Tax Consequences. Holders of restricted stock will recognize
ordinary income on the earlier of the date that the restricted stock is
transferable or is no longer subject to a substantial risk of forfeiture, in an
amount equal to the fair market value of the shares on that date. In certain
circumstances, a holder may elect to recognize ordinary income and determine
such fair market value on the date of the grant of the restricted stock. Holders
of restricted stock will also recognize ordinary income equal to their dividend
or dividend equivalent payments when such payments are received. Generally, the
amount of income recognized by participants will be a deductible expense for tax
purposes for Hudson River as long as Hudson River meets its federal tax
reporting obligations.

     Amendment to the RRP. The board of Hudson River may amend, suspend or
terminate the RRP or any portion thereof at any time, subject to New York State
Banking Board and FDIC Regulations, provided, however, that no such amendment,
suspension or termination shall impair the rights of any participant, without
his consent, in any award theretofore made pursuant to the RRP.

last two proposals are more fully discussed under the heading "Additional
Information Regarding the Hudson River Annual Meeting" on page ___.

Hudson River shareholders also may consider and vote upon any other matters that

any adjournment of the annual meeting. As of the date of this document, the
Hudson River board of directors is not aware of any other business to be
presented for consideration at the meeting.

Matters to be Considered at the Cohoes Special Meeting. At the Cohoes special
meeting, Cohoes shareholders will be asked to consider and vote upon the

Voting Rights of Shareholders; Votes Required for Approval

Voting Rights of Hudson River Shareholders. The Hudson River board of directors
has fixed the close of business on June 20, 2000 as the record date for
shareholders entitled to vote at the Hudson River meeting. Only holders of
record of Hudson River common stock on that record date are entitled to vote at
the meeting. Each share of Hudson

                                       42

<PAGE>



River common stock you own entitles you to one vote. On the Hudson River record
date, ___________ shares of Hudson River common stock were outstanding and
entitled to vote at the Hudson River annual meeting, held by approximately
________ shareholders of record.

Each participant in the Hudson River Employee Stock Ownership Plan instructs the
trustee how to vote his or her allocated shares. The trustee votes unallocated
shares in the manner directed by the majority of the allocated shares for which
it received instructions. If a participant does not give timely instructions,
the trustee votes the allocated shares in its discretion. Unvested shares under
Hudson River's 1998 Recognition and Retention Plan are voted by the trust
department of Hudson River's subsidiary bank.

Vote Required for Adoption of the Merger Agreement. The affirmative vote of the
holders of a majority of the Hudson River common stock is required to adopt the
merger agreement and approve the issuance of Hudson River common stock in the
merger. The Hudson River board unanimously recommends that Hudson River
shareholders vote "FOR" adoption of the merger agreement and approval of the
issuance of shares in the merger.

Because adoption of the merger agreement requires the affirmative vote of a
majority of the Hudson River common stock outstanding, abstentions and failure
to vote will have the same effect as votes against the merger. Under the Nasdaq
Stock Market rules, your broker may not vote your shares on the merger without
instructions from you. Without your voting instructions, a broker non-vote will
occur and will have the same effect as a vote against the merger.

The affirmative vote of the holders of a majority of the shares of Hudson River
common stock present and voting on the matter may approve all other proposals to
be considered at the Hudson River meeting except the election of directors,
which is done by a plurality of the votes cast. See "Additional Information
Regarding the Hudson River Annual Meeting" on page ____. A majority of shares
present may also authorize the adjournment of the Hudson River annual meeting.
No proxy that is voted against the merger will be voted in favor of adjournment
to solicit further proxies in favor of the merger.

Voting Rights of Cohoes Shareholders. The Cohoes board of directors has fixed
the close of business on June 22, 2000 as the record date for shareholders
entitled to notice of and to vote at the Cohoes special meeting. Only holders of
record of Cohoes common stock on the record date are entitled to vote at the
Cohoes special meeting. Each share of Cohoes common stock you own entitles you
to one vote. On the Cohoes record date, there were 7,912,255 shares of Cohoes
common stock outstanding and entitled to vote at the Cohoes special meeting,
held by approximately 4,600 shareholders of record.

Each participant in the Cohoes Employee Stock Ownership Plan instructs the
trustee how to vote his or her allocated shares. The trustee votes unallocated
shares in proportion to the votes of the allocated shares for which it received
instructions. If a participant does not give timely instructions, the trustee
votes the allocated shares in its discretion. Unvested shares under Cohoes' 1999
Recognition and Retention Plan are voted by Cohoes' board of directors.

Vote Required for Adoption of the Merger Agreement. The affirmative vote of the
holders of a majority of the Cohoes common stock outstanding is required to
adopt the merger agreement. The Cohoes board unanimously recommends that Cohoes
shareholders vote "FOR" adoption of the merger agreement.

Because approval of the Cohoes proposal to adopt the merger agreement requires
the affirmative vote of the holders of a majority of the Cohoes common stock
outstanding, abstentions and failures to vote will have the same effect as votes
against the merger. Under the Nasdaq Stock Market rules, your broker may not
vote your shares on the merger without instructions from you. Without your
voting instructions, a broker non-vote will occur and will have the same effect
as a vote against the merger.

The presence, in person or by proxy, of at least one-third of the total number
of shares of Cohoes common stock entitled to vote is required to constitute a
quorum at the special meeting. The affirmative vote of the holders of a majority
of the shares of Cohoes common stock present and voting on the matter may
authorize the adjournment of the meeting. No proxy that is voted against the
merger will be voted in favor of adjournment to solicit further proxies in favor
of the merger.

Voting of Proxies; Revocability of Proxies; Proxy Solicitation Costs

Voting of Proxies. You may vote in person at your meeting or by proxy. To ensure
your representation at the meeting, we recommend you vote by proxy even if you
plan to attend your meeting. You can always change your vote at the meeting.
Remember, if your shares are held in the name of a broker or other nominee, only
your broker or such nominee can vote your shares and only after receiving
instructions from you on how to vote the shares. Please contact the person
responsible for your account and instruct him or her to execute a proxy card on
your behalf.

Voting instructions are included on your proxy card. If you properly give your
proxy and submit it to us in time to vote, the persons named as your proxy will
vote your shares as you have directed. You may vote for or against the
proposal(s) set forth on your proxy card and described in this document or
abstain from voting. If you submit your proxy but do not make a specific choice
as to how to vote, your proxy will follow the Hudson River board's or Cohoes
board's recommendation and vote your shares "FOR" the proposal(s).

If any other matters are properly presented for consideration at the Hudson
River annual meeting or Cohoes special meeting, the persons named in the
relevant form of proxy will have the discretion to vote on those matters in
accordance with their best judgment. Neither Hudson River nor Cohoes is aware of
any other matters to be presented at its respective shareholders' meeting other
than those described in its notice of meeting.

You may receive more than one proxy card depending on how your shares are held.
For example, you may hold some of your shares individually, some jointly with
your spouse and some in trust for your children -- in which case you will
receive three separate proxy cards to vote.

Revocability of Proxies.  You may revoke your proxy before it is voted by:

     o    submitting a new proxy with a later date,

     o    notifying your company's secretary in writing before the meeting that
          you have revoked your proxy, or

     o    voting in person at your meeting.

If you plan to attend your company's meeting and wish to vote in person, we will
give you a ballot at the meeting. However, if your shares are held in the name
of your broker, bank or other nominee, you must bring a legal proxy from the
nominee, indicating that you were the beneficial owner of common stock on the
appropriate record date and giving you the right to vote those.

Proxy Solicitation Costs. We each will pay our own costs of soliciting proxies.
In addition to this mailing, Hudson River and Cohoes directors, officers and
employees may also solicit proxies personally, electronically or by telephone.
Hudson River is paying Regan & Associates a fee of $6,000 plus expenses to help
with the solicitation. Cohoes is paying Regan & Associates a fee of $7,000
including expenses to help with the solicitation. We will also reimburse brokers
and other nominees for their expenses in sending these materials to you and
obtaining your voting instructions.

Do not send in any stock certificates with your proxy cards. As soon as
practicable after the completion of the merger, the exchange agent will mail
transmittal forms with instructions for the surrender of stock certificates for
Cohoes common stock to former Cohoes shareholders.

        ADDITIONAL INFORMATION REGARDING THE HUDSON RIVER ANNUAL MEETING

In addition to the adoption of the merger agreement, Hudson River shareholders
are being asked to vote on the amendment of two benefit plans, the election of
three directors, and the ratification of auditors.

     Vote Required for Approval of Proposals Other than the Merger. The
presence, in person or by proxy, of at least one-third of the total number of
shares of common stock entitled to vote is required to constitute a

                                       44

<PAGE>



quorum at the meeting. Directors shall be elected by a plurality of the votes
cast. Approval of the amendment of the benefit plans and ratification of the
appointment of KPMG LLP requires the affirmative vote of the holders of a
majority of the votes cast. Abstentions and broker non-votes are counted for
purposes of determining a quorum at the meeting; however, abstaining shares will
have the same effect as a vote against the approval of the amendment of the
benefit plans and ratification of the auditor proposal while non-voted shares
will have no effect on the amendment of the benefit plans and ratification of
the auditor proposal. Abstentions and non-voted shares will have no effect on
the election of directors.

     Voting Securities and Certain Holders Thereof. The following table sets
forth information, as of June 20, 2000, regarding share ownership of (1) those
persons or entities known by management to beneficially own more than five
percent of the common stock, (2) each officer of Hudson River and its subsidiary
bank who made in excess of $100,000 (salary and bonus) during the 2000 fiscal
year; and (3) all directors and executive officers of Hudson River and of its
subsidiary bank as a group.

Election of Directors

Hudson River's board currently consists of nine members. The board is divided
into three classes, each of which contains one-third of the board. One-third of
the directors are elected annually. Directors of Hudson River are generally
elected to serve for a three-year period or until their respective successors
are elected and qualified.

The table below sets forth certain information, regarding the composition of
Hudson River's board, including their terms of office. It is intended that the
proxies solicited on behalf of the board (other than proxies in which the vote
is withheld as to any nominee) will be voted at the annual meeting FOR the
election of the nominees identified below. If any nominee is unable to serve,
the shares represented by all valid proxies will be voted for the election of
such substitute as the board may recommend. At this time, the board knows of no
reason why any nominee might be unable to serve, if elected. There are no
arrangements or understandings between the nominees and any other person
pursuant to which the nominees were selected other than the agreement to
nominate Mr. Giaquinto pursuant to the merger agreement between Hudson River and
SFS Bancorp, Inc. Assuming completion of the merger, the combined company's
board of directors will be made up of six directors named by Hudson River's
board and six directors named by Cohoes' board. Two directors from each party
will be assigned to each class.

     Employment Agreements. The bank entered into employment agreements with Mr.
Florio and four other officers of the bank and Hudson River entered into
employment agreements with Carl Florio, Sidney Richter and Timothy Blow. The
employment agreements ensure that the bank and Hudson River are able to maintain
a stable and competent management base. The continued success of the bank and
Hudson River depends to a significant degree upon the skills and competence of
the above referenced officers.

The employment agreements provide for either three-year or two-year terms for
each executive. The terms of the employment agreements are extended on a daily
basis unless written notice of non-renewal is given by the board. The employment
agreements provide that the executive's base salary is reviewed annually. In
addition to the base salary, the employment agreements provide for, among other
things, participation in stock benefit plans and other fringe benefits
applicable to executive personnel. The agreements provide for termination by the
bank or Hudson River for cause at any time. In the event the bank or Hudson
River chooses to terminate the executive's employment for reasons other than for
cause, or in the event of the executive's resignation from the bank and Hudson
River upon: (i) failure to re-elect the executive to his current offices; (ii) a
material change in the executive's functions, duties or responsibilities; (iii)
a reduction in the benefits and perquisites being provided to the executive
under the employment agreement; (iv) a liquidation or dissolution of the bank or
Hudson River; or (v) a breach of the agreement by the bank or Hudson River, the
executive or, in the event of death, his beneficiary would be entitled to
receive an amount equal to the remaining base salary payments due to the
executive for the remaining term of the employment agreement and the
contributions that would have been made on the executive's behalf to any
employee benefit plans of the bank and Hudson River during the remaining term of
the agreement. The bank and Hudson River would also continue and pay for the
executive's life, health, dental and disability coverage for the remaining term
of the agreement. Upon any termination of the executive, other than following a
change in control, the executive is subject to a one year non-competition
agreement.

Under the employment agreements, if voluntary or involuntary termination follows
a change in control of the bank or Hudson River, the executive or, in the event
of the executive's death, his beneficiary, would be entitled to the payment of
base salary, plan contributions and other forms of compensation to which the
executive would be entitled for the remaining term of the employment agreement
plus a severance payment equal to the greater of: (i) the payments due for the
remaining terms of the agreement; or (ii) three times the average of the five
preceding taxable years' annual compensation for Mr. Florio, and two times the
average of the five preceding taxable years' annual compensation for the four
other individuals. The bank and Hudson River would also continue the executive's
life, health, and disability coverage for thirty-six months for Messrs. Florio,
Richter and Blow, and twenty-four months for the other two individuals. Under
the employment agreements, a voluntary termination following a change in control
means the executive's voluntary resignation following any demotion, loss of
title, office authority or responsibility, a reduction in compensation or
benefits, or relocation. Notwithstanding that both

                                       50

<PAGE>

the bank and Hudson River employment agreements provide for a severance payment
in the event of a change in control, the executive would only be entitled to
receive a severance payment under one agreement.

Payments to the executive under the bank's employment agreement are guaranteed
by Hudson River in the event that payments or benefits are not paid by the bank.
Payment under Hudson River's employment agreement would be made by Hudson River.
Hudson River's employment agreement also provides that Hudson River compensates
the executive for excise taxes imposed on any "excess parachute payments," as
defined under section 280G of the Internal Revenue Code and any additional
income and excise taxes imposed as a result of such compensation. All reasonable
costs and legal fees paid or incurred by the executive pursuant to any dispute
or question of interpretation relating to the employment agreements shall be
paid by the bank or Hudson River, respectively, if the executive is successful
on the merits pursuant to a legal judgment, arbitration or settlement. The
employment agreements also provide that the bank and Hudson River shall
indemnify the executive to the fullest extent allowable under New York and
Delaware law, respectively. In the event of a change in control of the bank or
Hudson River, the total amount of payments due under the employment agreements,
based solely on cash compensation over the past five fiscal years paid to the
officers who received employment agreements and excluding any benefits under any
employee benefit plan or reimbursement for taxes which may be payable, would be
approximately $1.2 million.

     Change in Control Agreements. The bank entered into two-year Change in
Control (CIC) Agreements with eight officers of the bank, none of whom are
covered by employment agreements. Commencing on the first anniversary date and
continuing on each anniversary thereafter, the bank CIC Agreements may be
renewed by the board of the bank for an additional year. The bank's CIC
Agreements provide that in the event voluntary or involuntary termination
follows a change in control of Hudson River or the bank, the officer would be
entitled to receive a severance payment equal to two times the officer's average
base amount of cash compensation for the five most recent taxable years. The
bank would also continue to pay for the officer's life, health and disability
coverage for twenty-four months following termination. Under the CIC Agreements,
a voluntary termination following a change in control means the executive's
voluntary resignation following any demotion, loss of title, office authority or
responsibility, a reduction in compensation or benefits, or relocation. In the
event of a change in control of Hudson River or the bank, the total payments
that would be due under the CIC Agreements, based solely on the five year
average base amount of cash compensation paid to the officers covered by the CIC
Agreements and excluding any benefits under any employee benefit plan which may
be payable, would be approximately $1.0 million.

     Employee Severance Compensation Plan. The bank's board established the
Hudson River Bank & Trust Company Employee Severance Compensation Plan which
provides designated employees with severance pay benefits in the event of a
change in control of the bank or Hudson River. Management personnel with
employment agreements or CIC Agreements are not eligible to participate in the
severance plan. Generally, designated employees are eligible to participate in
the severance plan if they have completed at least one year of service with the
bank. The severance plan vests in each participant a contractual right to the
benefits such participant is entitled to thereunder. Under the severance plan,
in the event of a change in control of the bank or Hudson River, eligible
employees who are terminated from or terminate their employment within one year
(for reasons specified under the severance plan), are entitled to receive a
severance payment. If the participant, whose employment has terminated, has
completed at least one year of service, the participant is entitled to a cash
severance payment equal to the last two weeks of annual compensation immediately
preceding a change-in-control for each year of service up to a maximum of 100%
of annual compensation. Such payments may tend to discourage takeover attempts
by increasing costs to be incurred by the bank in the event of a takeover. In
the event the provisions of the Severance Plan are triggered, the total amount
of payments that would be due thereunder, based solely upon current salary
levels, would be approximately $276,000. However, it is management's belief that
certain of the bank's employees would be retained in their current positions in
the event of a change in control, and that any amount payable under the
severance plan would be considerably less than the total amount that could
possibly be paid under the severance plan.

     Benefit Plans. The bank currently provides health care benefits to its
employees, including hospitalization, major medical, dental, life and disability
insurance, subject to certain deductibles and copayments by employees.

                                       51

     Defined Benefit Pension Plan. The bank sponsors a defined benefit pension
plan for its employees. Salaried employees are eligible to participate in the
pension plan following the completion of one year of service (1,000 hours worked
during a continuous 12-month period) and attainment of 21 years of age. A
participant must reach five years of service before attaining a vested interest
in his or her retirement benefits, after which such participant is 100% vested.
The pension plan is funded solely through contributions made by the bank.

The benefit provided to a participant at normal retirement age (generally age
65) is based on the average of the participant's basic annual compensation
during the 36 consecutive months of service within the last 120 completed months
of a participant's service which yields the highest average compensation.
Compensation for this purpose is the participant's basic annual salary,
including any contributions through a salary reduction arrangement to a cash or
deferred plan, but exclusive of overtime, bonuses, severance pay, or any special
payments or other deferred compensation arrangements. The annual benefit
provided to a participant, without offset for the participant's anticipated
Social Security benefit, who retires at age 65 is equal to 2% of the executive's
highest average compensation for each year of service up to a maximum of 30
years.

The annual benefit provided to participants (i) at early retirement age
(generally age 62) with five years of service who elect to defer the payment of
their benefits to normal retirement age, (ii) at early retirement age with five
years of service who elect to receive payment of their benefits prior to normal
retirement age, or (iii) who postpone annual benefits beyond normal retirement
age, are calculated basically the same as the benefits for normal retirement
age, with the executive's highest average compensation being multiplied by 2%
for each year of such individual's actual years of service. A participant
eligible for early retirement benefits who does not meet the requirements set
forth above will have his or her benefits adjusted as further described in the
pension plan. The pension plan also provides for disability and death benefits.

The following table sets forth, as of March 31, 2000, estimated annual pension
benefits for individuals at age 65 payable in the form of a life annuity under
the most advantageous plan provisions for various levels of compensation and
years of service. The amounts in this table are based upon the assumption that
the Pension Plan continues in its present form and do not reflect offsets for
Social Security benefits and do not reflect benefits payable under the ESOP. At
March 31, 2000, the estimated years of credited service of Messrs. Florio,
Richter and Blow were seven, nine and three years, respectively.

*    Assumes that the participant had 30 or more years of credited service as of
     July 14, 1995.

For the 2000 plan year, the maximum compensation is limited to $160,000. The
maximum benefit payable under the qualified plan for the 2000 plan year is
$130,000.

     Benefit Restoration Plan. Hudson River also maintains a non-qualified
deferred compensation plan, known as the Benefit Restoration Plan. The Benefit
Restoration Plan provides certain officers and highly compensated executives of
Hudson River and the bank with supplemental retirement income when such amounts
cannot be paid from the tax-qualified 401(k) Plan or ESOP. Participants in the
Benefit Restoration Plan receive a benefit equal to the amount they would have
received under the Pension Plan, the 401(k) Plan and the ESOP, but for
reductions in such benefits imposed by operation of Sections 401(a)(17), 401(m),
401(k)(3), 402(g) and 415 of the Code. In addition, the Benefit Restoration Plan
is intended to make up benefits lost under the ESOP allocation

                                       52

procedures to certain participants named by the Compensation Committee who
retire prior to the complete repayment of the ESOP loan. At the retirement of a
participant, the restored ESOP benefits under the Benefit Restoration Plan are
determined by first: (1) projecting the number of shares that would have been
allocated to the participant under the ESOP if they had been employed throughout
the period of the ESOP loan (measured from the participant's first date of ESOP
participation); and (2) first reducing the number determined by (1) above by the
number of shares actually allocated to the participant's account under the ESOP;
and second, by multiplying the number of shares that represent the difference
between such figures by the average fair market value of the common stock over
the preceding five years. Benefit Restoration Plan participant's benefits are
payable upon the retirement or other termination of service of the participant
in the form of a lump sum. Payment of a deceased participant's benefits will be
made to his or her designated beneficiary.

     Stock Based Benefit Plans. Hudson River's 1998 Stock Option and Incentive
Plan and its 1998 Recognition and Retention Plan are discussed on pages __ and

     Compensation Committee Report on Executive Compensation. In fulfillment of
SEC requirements for disclosure in proxy materials of the Compensation
Committee's policies regarding compensation for executive officers, the
committee has prepared the following report for inclusion in this proxy
statement.

Decisions on compensation of Hudson River's executives are made by the
Compensation Committee of the board. Each member of the committee is a
non-employee director. The committee believes that the actions of each executive
officer have the potential to impact the short-term and long-term profitability
of Hudson River. Consequently, the committee places considerable importance on
its task of designing and administering an executive compensation program.

     Compensation Policy. The Compensation Committee has developed an executive
compensation policy designed to (1) offer competitive compensation to attract,
motivate, retain and reward executive officers who are crucial to the long-term
success of Hudson River; and (2) encourage decision-making that maximizes
long-term shareholder value. The Compensation Committee has sought to consider a
multitude of factors establishing appropriate levels of compensation for
executive officers, with no one factor clearly overshadowing all the others.

The compensation package provided to the executive officers of Hudson River is
composed principally of base salary and cash and stock-based incentive awards.
Executive officers also participate in other benefit plans available to all
eligible employees, including the ESOP.

The Compensation Committee considers a variety of factors in determining
executive compensation. These factors generally fall into two categories, those
that relate to specific work performed and expected of the officer and those
that relate to Hudson River, the bank, the local business economic conditions
and other general matters. In the former category, the Committee considers,
among other factors, the level of responsibility of each officer; the expertise
and skill level required to perform the position; satisfaction of prior period
goals and objectives; length of service; the complexity of work that may be
required in connection with strategic plans or special projects; and prior
compensation history. In the latter category, the Committee considers, among
other factors, Hudson River's earnings, capital and asset size; the results of
government regulatory examinations; the bank's regulatory ratings on safety and
soundness as well as Community Reinvestment Act examinations; and performance
and compensation programs of peer group banks.

Employee benefit plans represent an important component of any compensation
package. The defined benefit pension plan and health insurance benefits
available to all employees, including executive officers, provide competitive
benefits comparable to those available at other institutions. Stock-based
compensation plans, including the ESOP, the 1998 Stock Option and Incentive Plan
and the 1998 Recognition and Retention Plan, provide employees, including
executive officers, with additional equity-based incentives to maximize
long-term shareholder value. Cash bonuses are used to provide incentives to both
executive officers and other employees in relation to specific projects or
additional responsibilities.

The Compensation Committee's decisions are discretionary and are based upon
subjective factors. No mathematical or similar objective formula is used to
determine any compensation package. The Compensation

                                       53

<PAGE>



Committee believes that a competitive employee benefit package is essential to
achieving the goals of attracting and retaining highly qualified employees.

     Chief Executive Officer. Total annual compensation paid to Carl A. Florio,
President and Chief Executive Officer, for fiscal 2000 was $244,538 as detailed
in the above compensation table and reflects a 3% increase from fiscal 1999. In
determining total compensation paid to the Chief Executive Officer, including
his benefits under the Benefit Restoration Plan, the Compensation Committee
considered the factors discussed above and also considered a number of specific
matters including stock-based compensation and benefit plans awarded or made
available to chief executive officers of other thrift institutions.

     This report is included herein at the direction of the Compensation
Committee members.

                                Joseph W. Phelan

comparing the cumulative total return on Hudson River's common stock to the
cumulative total return of the Nasdaq Bank Index and the S&P 500 Index for each
quarterly period from July 1, 1998 (the date Hudson River's common stock was
first reported on the Nasdaq Stock Market) through March 31, 2000. The
presentation assumes $100 was invested on July 1, 1998 in Hudson River's common
stock at a price of $10.00 per share, the subscription offering price in Hudson
River's initial public offering.

     Certain Transactions. The bank's policies do not permit the bank to make
loans to any of its directors. Federal laws require that all loans or extensions
of credit to executive officers and directors must be made on substantially the
same terms, including interest rates and collateral, as those prevailing at the
time for comparable transactions with the general public and must not involve
more than the normal risk of repayment or present other unfavorable features. As
of March 31, 2000, all outstanding loans to the bank's executive officers were
made in the ordinary course of business and on the same terms, including
collateral and interest rates, as those prevailing at the time for comparable
transactions with the general public, and do not involve more than the normal
risk of collectiblity.

The chairman of the board, Earl Schram, Jr., is president of the law firm of
Connor, Curran & Schram P.C. Connor Curran serves as outside counsel to the bank
and performs various legal services for the bank. During fiscal 2000, the bank
paid Connor Curran approximately $195,245 in fees for services rendered. Connor
Curran also receives an indirect benefit from the bank to the extent borrowers
of the bank engage Connor Curran to close their loans. Services provided by
Connor Curran to the bank are provided on terms comparable to those which are
available to unaffiliated parties.

2.3 Closing

         Within  30  days  following  the  satisfaction  or  waiver  of all  the
conditions  set forth in Article VII (other than the  delivery of  certificates,
opinions and other  instruments  and documents to be furnished at Closing),  the
Closing shall take place on a date and at a time and place  mutually  designated
in writing  by the  Parties.  The  Certificate  of Merger  shall be filed on the
Closing Date.

2.4 Treatment of Capital Stock

         Subject to the  provisions of this  Agreement,  at the Effective  Time,
automatically  by virtue of the Merger and without any action on the part of any
person or entity:

                  (a) Each share of Hudson Common Stock shall continue unchanged
         as a share of Surviving Corporation Common Stock.

                  (b) All  Cohoes-Owned  Shares  shall be  canceled  and retired
         without consideration or conversion.

                  (c) Each other  outstanding share of Cohoes Common Stock shall
         be converted into the right to receive the Merger Consideration.

2.5 Shareholder Rights; Stock Transfers

         At the Effective Time,  holders of  Certificates  shall cease to be and
shall have no rights as shareholders of Cohoes.  After the Effective Time, there
shall be no transfers on the stock transfer books of Cohoes. If Certificates are
presented for transfer after the Effective  Time, they shall be delivered to the
Surviving  Corporation or the Exchange Agent for cancellation  against delivery,
without interest, of the Merger Consideration.

2.6 Fractional Shares

         No  fractional  shares of  Surviving  Corporation  Common Stock will be
issued in the  Merger;  instead,  the  Surviving  Corporation  shall pay to each
Certificate  holder who would  otherwise  be entitled to a  fractional  share an
amount in cash (without interest) determined by multiplying such fraction by the
closing sale price of Hudson Common Stock,  as reported by the Nasdaq  reporting
system (as reported in The Wall Street Journal or, if not reported  therein,  in
another authoritative source), for the


                                       13

<PAGE>




last  trading  day  immediately  preceding  the  Closing  Date.  No  dividend or
distribution  with  respect to Hudson  Common  Stock shall be payable on or with
respect to any fractional share interest,  and no such fractional share interest
shall entitle the owner thereof to vote or to any other rights of a shareholder.
For the purposes of determining any such fractional share interests,  all shares
of Surviving  Corporation  Common Stock to be issued to a Cohoes  shareholder in
the Merger  shall be combined  so as to  calculate  the maximum  number of whole
shares  of  Surviving   Corporation   Common  Stock   issuable  to  such  Cohoes
shareholder.

2.7 Options

         At the Effective  Time, each then  outstanding  Cohoes Option which was
also  outstanding  on  the  date  hereof  shall  be  assumed  by  the  Surviving
Corporation,  shall continue to be outstanding, and shall represent an option to
purchase  Surviving  Corporation  Common  Stock  subject  to the same  terms and
conditions,  but in an amount and at an exercise  price  determined  as provided
below:

                  (a) the number of shares of Surviving Corporation Common Stock
         to be subject to the continuing option shall be equal to the product of
         the  number of shares of Cohoes  Common  Stock  subject  to the  Cohoes
         Option  immediately prior to the Effective Time and the Exchange Ratio,
         rounded to the nearest whole share; and

                  (b) the  exercise  price  per share of  Surviving  Corporation
         Common Stock under the continuing option shall be equal to the exercise
         price  per  share of  Cohoes  Common  Stock  under  the  Cohoes  Option
         immediately  prior to the Effective Time divided by the Exchange Ratio,
         rounded to the nearest whole cent.

         It is  intended  that the  foregoing  assumption  shall  be  undertaken
consistent with and in a manner that will not constitute a "modification"  under
Section 424 of the Code as to any Cohoes  Option  which is an  "incentive  stock
option".

2.8 Exchange Procedures

                  (a) At or prior to the  Effective  Time,  Hudson shall deposit
         with the Exchange Agent certificates  representing  shares of Surviving
         Corporation   Common  Stock  (and  an  estimated  amount  of  cash  for
         fractional shares) equal to the aggregate Merger Consideration.

                  (b) As promptly as practicable  after the Effective  Time, the
         Exchange  Agent  shall send  transmittal  materials  to each  holder of

         risk of loss and title to Certificates  shall pass only upon acceptance
         of such  Certificates  by the  Surviving  Corporation  or the  Exchange
         Agent.  Upon  acceptance  of a  Certificate  (or  indemnity  reasonably
         satisfactory  to the Surviving  Corporation  and the Exchange Agent, if
         any of such  Certificates  are lost,  stolen or destroyed) the Exchange
         Agent shall deliver the Merger Consideration. The Surviving Corporation
         and the Exchange Agent shall be entitled to conclusively  rely upon the
         stock  transfer  books of  Cohoes  to  establish  the  identity  of the
         Certificate  holders.  In  the  event  of a  dispute  with  respect  to
         ownership of any Certificate, the Surviving Corporation or the Exchange
         Agent shall be entitled to deposit any consideration in respect thereof
         in escrow with an  independent  third party and  thereafter be relieved
         with respect to any claims thereto.

                  (c) Neither the  Exchange  Agent nor any Party shall be liable
         to any Certificate holder for any amount properly delivered to a public
         official pursuant to applicable abandoned property,  escheat or similar
         laws.

                  (d)  No  holder  of  an  unsurrendered  Certificate  shall  be
         eligible to receive dividends or distributions on Surviving Corporation
         Common Stock. Upon exchange of a Certificate for Surviving  Corporation
         Common  Stock,  the holder  thereof  shall be  entitled  to receive any
         dividends or distributions,  without interest,  declared and paid after
         the Effective Time.

                  (e) Any cash and certificates for Surviving Corporation Common
         Stock which remain  unclaimed six months after the Effective Time shall
         be returned to the  Surviving  Corporation.  Certificate  holders shall
         thereafter  look only to the Surviving  Corporation  for payment of the
         Merger


                                       15

acts are  necessary or desirable to (i) vest,  perfect or confirm,  of record or
otherwise,  in the Surviving  Corporation its right, title or interest in, to or
under  any of the  rights,  properties  or  assets  of  Cohoes  acquired  by the

possession of such rights, properties or assets in the Surviving Corporation and
otherwise to carry out the purposes of this  Agreement;  and the proper officers

Cohoes or otherwise to take any and all such action.

         not been audited by the applicable tax  authorities and no deficiencies
         for any tax,  assessment  or  governmental  charge have been  proposed,
         asserted or assessed  (tentatively or otherwise)  against it which have
         not been settled and paid.  There are currently no agreements in effect
         with  respect  to it to  extend  the  period  of  limitations  for  the
         assessment  or  collection  of  any  tax.  No  audit,   examination  or
         deficiency  or refund  litigation  with  respect to any such  return is
         pending or, subject to the Knowledge Qualification, threatened.

         allocation  or sharing  of taxes,  (ii) is not  required  to include in
         income any  adjustment  pursuant  to  Section  481(a) of the Code or by
         reason  of any  change  in  accounting  method  (nor  does it have  any
         knowledge  that the IRS has proposed any such  adjustment  or change of
         accounting  method)  and  (iii) has not  filed a  consent  pursuant  to
         Section  341(f) of the Code or agreed to have Section  341(f)(2) of the
         Code apply.

                  (d) It has withheld amounts from its employees,  shareholders,
         and  holders of public  deposit  accounts  in  compliance  with the tax
         withholding provisions of applicable federal, state and local laws, has
         filed all federal,  state and local returns and reports for all periods
         for which such  returns or reports  would be due with respect to income
         tax withholding,  social security, unemployment taxes, income and other
         taxes and all payments or deposits with respect to such taxes have been
         timely made.

                  (d)  There  is  no  pending  or,   subject  to  the  Knowledge
         Qualification,  threatened legal action,  suit or claim relating to any

                  (e) It has not  engaged in a  transaction,  or omitted to take
         any  action,  with  respect  to any  Employee  Plan  that  has or would
         reasonably  be  expected  to subject it to a tax or penalty  imposed by
         either  Section 4975 of the Code or Section 502 of ERISA,  assuming for
         purposes  of Section  4975 of the Code that the  taxable  period of any
         such transaction expired as of the date hereof.

                  (f) No  liability  (other  than for payment of premiums to the
         PBGC  which  have  been made or will be made on a timely  basis)  under

         respect to any ongoing,  frozen or terminated  "single-employer  plan",
         within the  meaning  of  Section  4001(a)(15)  of ERISA,  currently  or

         Section  4001(a)(14)  of ERISA or Section 414(b) or (c) of the Code (an
         "ERISA Affiliate Plan").

         not been waived, has been required to be filed for any Employee Plan or
         by any ERISA  Affiliate  Plan within the 12-month  period ending on the
         date hereof.  The PBGC has not instituted  proceedings to terminate any
         Pension  Plan or ERISA  Affiliate  Plan and,  subject to the  Knowledge
         Qualification,  no  condition  exists  that  presents  a risk that such
         proceedings will be instituted by the PBGC.

                  (i) There is no pending investigation or enforcement action by

                  (j) Under each Pension Plan and ERISA Affiliate Plan that is a
         defined  benefit  plan,  as of the  date of the most  recent  actuarial
         valuation   performed  prior  to  the  date  hereof,   the  actuarially
         determined  present  value of all  "benefit  liabilities",  within  the
         meaning of Section  4001(a)(16) of ERISA (as determined on the basis of
         the actuarial assumptions contained in such actuarial valuation of such
         Pension Plan or ERISA Affiliate  Plan), did not exceed the then current
         value of the assets of such  Pension Plan or ERISA  Affiliate  Plan and
         since such date there has been neither a material adverse change in the
         financial  condition of such Pension Plan or ERISA  Affiliate  Plan nor
         any  amendment or other change to such Pension Plan or ERISA  Affiliate
         Plan that  would  increase  the  amount of  benefits  thereunder  which
         reasonably could be expected to change such result.

                  (k) All  contributions  required to be made under the terms of
         any Employee Plan or ERISA Affiliate Plan have been timely made.

                  (l) Neither any Pension Plan nor any ERISA  Affiliate Plan has
         an "accumulated  funding deficiency" (whether or not waived) within the
         meaning  of  Section  412 of the Code or  Section  302 of ERISA and all
         required  payments  to the PBGC with  respect to each  Pension  Plan or
         ERISA Affiliate Plan have been made on or before their due dates.

                  (m) Neither it nor any ERISA  Affiliate (i) has  provided,  or
         would reasonably be expected to be required to provide, security to any
         Pension  Plan  or to any  ERISA  Affiliate  Plan  pursuant  to  Section
         401(a)(29)  of the Code,  or (ii) has taken any  action,  or omitted to
         take any action, that has resulted,  or would reasonably be expected to
         result, in the imposition of an Encumbrance under Section 412(n) of the
         Code or pursuant to ERISA.

                  (n) It has no  obligation to provide  retiree  health and life
         insurance or other  retiree  death  benefits  under any Employee  Plan,
         other than benefits  mandated by Section  4980B of the Code.  There has
         been  no  communication  to its  employees  that  would  reasonably  be
         expected to promise or guarantee such employees  retiree health or life
         insurance or other retiree death benefits.

                  (o) It has neither made any payments, nor is obligated to make
         any payments by virtue of the  consummation of any of the  Transactions
         or otherwise,  nor a party to any agreement or any Employee Plan,  that
         under any  circumstances  could  obligate it or its  successor  to make
         payments or deemed  payments that (i) are not or will not be deductible
         because  of  Sections  162(m) or 280G of the Code or (ii)  require  the
         Surviving  Corporation or any of its  Subsidiaries to record any charge
         or  expense  therefor  (or any tax  gross-up  payments)  for  financial
         reporting purposes on a post-acquisition  basis.  Neither the execution
         of  this  Agreement  nor  the  consummation  of the  Transactions  will
         constitute  a change  in  control  for  purposes  of any of the  Hudson
         Employee Plans or any of the employment  agreements,  change in control
         severance   agreements,   severance   compensation   plan  or   benefit
         restoration plan to which Hudson or any of its Subsidiaries is a party.

                  which do not  adversely  affect  the value or use of such real
                  property, and

                           (iv)  any  monetary  Encumbrances,  reflected  in its

         present and former  directors and officers,  its  shareholders and such
         other matters as may be reasonably necessary or advisable in connection

                  (c) Each Party  shall  promptly  furnish  the other Party with

         Subsidiaries  properties  and  personnel,  and shall  disclose and make
         available  upon  reasonable  request to the extent such  disclosure  is
         permitted by law and will not result in the loss or  potential  loss of
         any attorney-client  privilege,  all books, papers and records relating
         to its  and  its  Subsidiaries  assets,  stock  ownership,  properties,
         operations, obligations and liabilities, including all books of account

         such access and any such reasonable request shall be reasonably related
         to  the  Transactions  and  shall  not  unduly  interfere  with  normal
         operations  of the other Party and its  Subsidiaries.  Each Party shall
         make its  directors,  officers,  employees  and agents  and  authorized
         representatives  (including counsel and independent public accountants)

                  (b) All  information  furnished  previously in connection with
         the  Transactions  or  pursuant  hereto  shall be  treated  as the sole

         information  shall either destroy or return to the furnishing Party all
         documents or other  materials  containing,  reflecting  or referring to
         such  information,  shall use its best efforts to keep confidential all
         such  information,  and  shall  not  directly  or  indirectly  use such
         information  for any  competitive  or other  commercial  purposes.  The
         obligation to keep such  information  confidential  shall  continue for
         five years from the date of this  Agreement  but shall not apply to (i)
         any  information  which (x) the Party  receiving  the  information  can
         establish was already in its possession prior to the disclosure thereof
         by the other Party; (y) was then generally known to the public;  or (z)
         became known to the public through no fault of the Party  receiving the
         information;  or (ii) disclosures pursuant to a legal requirement or in
         accordance

         Party which is the subject of any such legal requirement or order shall

press release  related to this Agreement or the  Transactions,  and consult with
each other as to the form and  substance of other public  disclosures  which may
relate to the  Transactions,  provided,  however,  that nothing contained herein
shall prohibit either Party,  following  notification  to the other Party,  from
making  any  disclosure  which  such  Party  believes  is  required  by  law  or
regulation.

6.6 Business of the Parties

                  (a)  During  the period  from the date of this  Agreement  and
         continuing until the Effective Time,  except as expressly  contemplated
         or permitted by this Agreement or with the prior written consent of the
         other  Party,  each Party  shall  carry on its  business  and cause its
         Subsidiaries  to carry on their  businesses only in the ordinary course
         consistent with past practice. During such period, each Party also will

         available  the present  services of its  employees and (z) preserve the
         goodwill of its customers  and others with whom business  relationships
         exist.  Without  limiting the generality of the foregoing,  except with
         the  prior  written   consent  of  the  other  Party  or  as  expressly
         contemplated  hereby,  between the date hereof and the Effective  Time,
         neither Party nor any of its Subsidiaries shall:

                           (i) declare,  set aside,  make or pay any dividend or
                  other distribution  (whether in cash, stock or property or any

                  for (A) the declaration and payment of regular  quarterly cash
                  dividends  by Cohoes  in an amount  not in excess of $0.07 per

                  Parties'  past  dividend  practices;   provided  however,  the
                  declaration of the last quarterly  dividend by Cohoes prior to
                  the   Effective   Time  and  the  payment   thereof  shall  be
                  coordinated  with,  and  subject  to the  approval  of  (which
                  approval will not be unreasonably  withheld),  Hudson so as to
                  preclude any  duplication of dividends (it being the intention
                  of the Parties that  holders of Cohoes  Common Stock shall not
                  receive a dividend from both Parties  relating to such period,
                  or fail to receive one dividend relating to such period);  and

                  owned Subsidiary of a Party to such Party;

                  programs Previously  Disclosed in amounts consistent with past
                  practices  (even  though the  amounts  thereof  are subject to
                  Board discretion and have not been heretofore

directors,  officers,  employees,  representatives  or agents  shall  solicit or
encourage  inquiries  or  proposals  with  respect to,  furnish any  information

such information (but limited to the information  provided to the other Party in
connection  with  or  relating  to  this  Agreement  and  the  Transactions)  or
participate in such  negotiations  or  discussions  if such Board,  after having
consulted with and considered the advice of outside counsel, has determined that
the  failure  to do the same  would,  in the good faith  opinion of such  Board,

Party will  promptly  inform the other  Party  orally and in writing of any such
request  for  information  or of any  negotiations  or  discussions,  as well as
instruct its  directors,  officers,  employees,  representatives  and agents and

6.9 Indemnification

         (a)  After  the  Effective  Time,  the  Surviving   Corporation   shall
indemnify,  defend and hold  harmless each person who is now, or who has been at
any time before the date hereof or who becomes  before the  Effective  Time,  an
officer,  director  or  employee  of  either  Party  or any  of  its  respective
Subsidiaries (the "Indemnified  Parties") against all losses,  claims,  damages,
costs, expenses (including attorney's fees), liabilities or


                                       40

<PAGE>




judgments or amounts that are paid in settlement (which settlement shall require
the prior written consent of the Surviving Corporation,  which consent shall not
be  unreasonably  withheld) of or in connection  with any claim,  action,  suit,
proceeding or investigation,  whether civil, criminal, or administrative (each a
"Claim"), in which an Indemnified Party is, or is threatened to be made, a party
or a witness  based in whole or in part on or arising in whole or in part out of
the fact that such  person is or was a  director,  officer or employee of either
Party or any of its respective Subsidiaries if such Claim pertains to any matter
or fact arising,  existing or occurring  before the Effective  Time  (including,
without  limitation,  the  Transactions,  regardless  of  whether  such Claim is
asserted or claimed before, or at or after, the Effective Time (the "Indemnified
Liabilities"), to the fullest extent permitted under applicable state or federal
law in effect as of the date  hereof or as amended  applicable  to a time before
the Effective Time and under such Party's  Charter or bylaws as in effect on the
date hereof (as the case may be). The Surviving  Corporation  shall pay expenses
in advance of the final  disposition  of any such action or  proceeding  to each
Indemnified  Party to the full extent  permitted by applicable  state or federal
law in effect as of the date  hereof or as amended  applicable  to a time before
the Effective Time upon receipt of any  undertaking  required by applicable law.
Any  Indemnified  Party  wishing to claim  indemnification  under  this  Section
6.9(a), upon learning of any Claim, shall notify the Surviving  Corporation (but
the failure so to notify the Surviving Corporation shall not relieve it from any
liability  which it may have under this Section  6.9(a)except to the extent such
failure  materially  prejudices the Surviving  Corporation) and shall deliver to
the  Surviving  Corporation  any  undertaking  required by  applicable  law. The
Surviving  Corporation  shall ensure,  to the extent  permitted under applicable
law,  that all  limitations  of liability  existing in favor of the  Indemnified
Parties as provided in a Party's  Charter or  bylaws(as  the case may be), as in
effect as of the date hereof,  or allowed under  applicable state or federal law
as in effect as of the date hereof or as such law may be amended applicable to a
time before the Effective  Time, with respect to Indemnified  Liabilities  shall
survive the consummation of the Transactions.

         (b) From and after the  Effective  Time,  the  directors,  officers and
employees of each Party hereto or any of its Subsidiaries who become  directors,
officers or employees of the Surviving  Corporation or any of its  Subsidiaries,
shall have


                                       41

<PAGE>




indemnification  rights having  prospective  application with respect to acts or
omissions  occurring after the Effective  Time. The prospective  indemnification
rights shall consist of such rights to which  directors,  officers and employees
of the  Surviving  Corporation  and its  Subsidiaries  are  entitled  under  the
provisions  of the  Charter  and  bylaws of the  Surviving  Corporation  and its
Subsidiaries,  as in effect  from  time to time  after the  Effective  Time,  as
applicable, and provisions of applicable state and federal law as in effect from
time to time after the Effective Time.

         (c) For a period of six years from and after the  Effective  Time,  the
Surviving  Corporation  shall  cause to be  maintained  in  effect  the  current
policies of directors' and officers'  liability  insurance  maintained by Cohoes
and its  Subsidiaries  (provided that the Surviving  Corporation  may substitute
therefor  policies  from a  financially  capable  insurer  of at least  the same
coverage and amount  containing terms and conditions which are  substantially no
less  advantageous,  or in the event such coverage is provided  through Hudson's
insurer it may be on terms and  conditions  (other than  coverage  and  amounts)
consistent with Hudson's current coverage), or in lieu thereof single limit tail
coverage  for such period,  with respect to claims  arising from facts or events
which occurred before the Effective Time. Following  consummation of the Merger,
the  directors and officers of the Surviving  Corporation  and its  Subsidiaries
shall be covered by the directors' and officers' liability insurance  maintained
by the Surviving Corporation and its Subsidiaries.

         (d)  The  obligations  of  the  Surviving  Corporation  provided  under
paragraphs  (a), (b) and (c) of this Section 6.9 are intended to be  enforceable
against the Surviving  Corporation directly by the Indemnified Parties and shall
be binding on all respective  successors and permitted  assigns of the Surviving
Corporation.

         If requested by a Party within 15 days after the date hereof (or within
15 days after the  acquisition or lease of any real property  acquired or leased
after  the  date  hereof),   the  other  Party  shall,  as  soon  as  reasonably
practicable, but not later than 30 days from the receipt of the request, Deliver
a report of a phase one  environmental  investigation  on real property owned or

branch  facilities  or other office uses where the space leased  comprises  less
than 20% of the total space leased to all tenants of such property). If required
by  the  phase  one  environmental   investigation  in  the  requesting  Party's
reasonable opinion, the other Party shall Deliver, within 60 days of the receipt
of  the  request,  a  report  of a  phase  two  environmental  investigation  on
properties  requiring such additional study. The requesting Party shall have ten
days from its receipt of the phase one environmental  investigation to request a
phase  two   environmental   investigation.   The  costs  of  any  environmental

6.11 Employees and Employee Benefit Plans

                  (a) Full time  employees  of Cohoes and its  Subsidiaries  who
         remain   employed   after  the  Effective  Time  will  be  eligible  to
         participate  in  benefit  plans of the  Surviving  Corporation  and its
         Subsidiaries that are generally  available to their full-time employees
         on a  uniform  and  non-discriminatory  basis  in  accordance  with and
         subject to the terms and provisions of such benefit plans,  with credit
         for years of service with Cohoes and its  Subsidiaries  for the purpose
         of determining  eligibility for participation,  vesting and entitlement
         to  vacation  time and sick pay (but not for the  purpose of accrual or
         restoration  of benefits  under any Hudson  Employee Plan or any future
         benefit plan of the Surviving  Corporation  or any of its  Subsidiaries
         where  benefits are  calculated  on an actuarial  basis,  including any
         qualified or non-qualified  defined benefit plan or restoration  plan).
         Contributions to (and accrual of benefits, to the extent applicable, if
         any,  under)  benefit  plans  of  the  Surviving  Corporation  and  its
         Subsidiaries on behalf of continuing  full-time employees of Cohoes and
         its Subsidiaries shall only relate to qualifying compensation earned by
         such  employees  after  the  Effective  Time  subject  to the terms and
         provisions of such employee plans.  Notwithstanding  anything contained
         above,  continuing  full time employees of Cohoes and its  Subsidiaries
         shall  not  be  eligible  to  participate  in  the  Hudson   (Surviving
         Corporation)  ESOP until the plan year  beginning  April 1,  2001.  The
         Surviving  Corporation  shall use its best efforts to cause any and all
         pre-existing  condition limitations (to the extent such limitations did
         not apply to a pre-existing  condition under the  corresponding  Cohoes
         group  health plan) and  eligibility  waiting  periods  under its group
         health plans


                                       43

<PAGE>




         to be waived with respect to such participants and their
         eligible dependents.

                  (b) If the  employment  of any  full-time  employee of Cohoes,
         Hudson or their  respective  Subsidiaries is  involuntarily  terminated
         other than for Cause within six months  following the  Effective  Time,
         the Surviving  Corporation or its applicable  Subsidiary  shall provide
         severance  benefits to such  employee  in a cash  amount  equal to such
         employee's   regular  salary  for  a  one-week  period  (as  in  effect
         immediately prior to the Effective Time) multiplied by the total number
         of whole years of such employee's full-time employment (up to a maximum
         of  thirteen  years)  at  Cohoes,  Hudson  or any of  their  respective
         Subsidiaries;  provided,  however that in no event shall the  Surviving
         Corporation or any of its applicable  Subsidiaries  have any obligation
         to provide  severance  benefits to any such  full-time  employee  whose
         termination  of employment  occurs due to  resignation or discharge for
         Cause  or who is  entitled  to  severance  benefits  or the  equivalent
         thereof  under the terms of any other  compensation  plan or individual
         contract or the provisions of Section 6.11(c).

                  (c) The Surviving Corporation agrees to honor the terms of all
         Previously Disclosed employment,  consulting, severance and termination
         agreements,  severance plans,  benefit  restoration plans, stock option
         plans, and recognition and retention plans to which Cohoes or Hudson or
         any of their respective  Subsidiaries is a party, other than those that
         are being  terminated  and/or replaced at the Effective  Time.  Nothing
         herein is intended to limit the right of the Surviving  Corporation  to
         amend or terminate any of the foregoing in accordance with their terms.
         The Surviving  Corporation  hereby  expressly  assumes at the Effective
         Time  every  such  agreement  which  by  its  terms  requires   express
         assumption  by a  successor.  Such  express  assumption  shall occur by
         virtue of  Hudson's  execution  of this  Agreement  without any further
         action required by the Surviving Corporation upon the completion of the
         Merger.  Each Cohoes  employee  who is currently a party to a change in
         control severance agreement with Cohoes' savings bank Subsidiary and is
         employed  at the  Effective  Time  shall be  offered  at such  time the
         opportunity to receive a new change in control severance agreement from
         the Surviving  Corporation in replacement  thereof in the same form and
         with the same benefits contained in the change in control


                                       44

<PAGE>




         severance  agreements currently in effect at Hudson in consideration of
         such employee  waiving,  relinquishing  and releasing all of his rights
         under his existing change in control  severance  agreement with Cohoes'
         savings  bank  Subsidiary  unless  his  employment  with the  Resulting
         Institution is involuntarily  terminated without cause by the Resulting
         Institution  within one year after the  Effective  Time,  in which case
         such employee shall remain  entitled to receive the severance and other
         benefits  contained in his or her current  change in control  severance
         agreement with Cohoes' savings bank Subsidiary.  Any employee of Hudson
         or its savings bank  Subsidiary  who  currently has a change in control
         severance  agreement  with Hudson  shall,  if his or her  employment is
         involuntarily  terminated by the Surviving Corporation or the Resulting
         Institution  without cause within one year after the Effective Time, be
         entitled  to receive  benefits  equal to one year's base salary in lump
         sum on the  date  of  employment  termination  plus  continuing  health
         insurance  coverage(including spousal and dependant coverage) under the
         Surviving Corporation's group health insurance plan during the one year
         period after the date of employment termination with all premiums being
         paid by the Surviving Corporation.

                  (d) In the  sole  discretion  of  the  Surviving  Corporation,
         payments  made  by  it  or  its   Subsidiaries  in  full  and  complete
         satisfaction  of  obligations of Cohoes or its  Subsidiaries  under any
         Cohoes  Employee Plan, or severance  under Section 6.11(b) or under any
         agreement  or  arrangement  referred  to in  Section  6.11(c)  shall be
         subject to the recipient's delivery to the Surviving Corporation of (i)
         a written  acknowledgment  signed by such recipient that the payment or
         payments  and benefits to be made to him or her is in full and complete
         satisfaction of all  liabilities and obligations  thereunder of Cohoes,
         the Surviving Corporation,  and each of their respective  Subsidiaries,
         affiliates,  directors,  officers,  employees  and  agents,  and (ii) a
         release by such recipient of all such parties from further liability in
         connection  with the particular  Cohoes  Employee Plan, the recipients'
         employment, agreement or arrangement, as applicable.

                  (e)  Prior  to the  Closing,  Cohoes  shall  make  appropriate
         amendments  to the Cohoes  ESOP,  to the extent  permitted  by law,  to
         permit the Surviving  Corporation  Common Stock  received by the Cohoes
         ESOP in the Merger to be tendered to


                                       45

<PAGE>




         the Surviving  Corporation for redemption and/or  cancellation  against
         payment  and  retirement  of the  Cohoes  ESOP  loan  by the  Surviving
         Corporation(in   the  same  manner  as  if  such  shares  of  Surviving
         Corporation Common Stock received in the Merger by the Cohoes ESOP were
         sold by it in the open market with the cash  proceeds  therefrom  being
         utilized to retire the Cohoes ESOP loan).  At the Effective  Time,  the
         Cohoes ESOP shall terminate in accordance with its terms based upon the
         Merger  constituting  a change in control  termination  therein and the
         Surviving  Corporation  shall  not take any  action  to  preclude  such
         termination.   Moreover,  the  Parties  shall  make  all  filings  with
         Governmental Entities relating to the termination of the Cohoes ESOP to
         facilitate  the  repayment  of the ESOP  loan and the  distribution  of
         benefits  to   participants   thereunder,   if  any,  at  the  earliest
         practicable time after the Effective Time.

                  (f) At any time on or after the  Effective  Time as determined
         by the  Surviving  Corporation,  the Cohoes 401(k) Plan shall be merged
         into the Hudson  401(k)  Plan,  with the Hudson  401(k)  Plan being the
         surviving plan, all in accordance  with  applicable  law,  provided the
         Parties  understand  and agree that there is no intention on their part
         for the profit  sharing  plan  portion of the Cohoes  401(k) Plan to be
         continued  in  the  surviving  plan.  Cohoes  shall  take  all  actions
         requested  by Hudson in order to  accomplish  the  merger of the Cohoes
         401(k) Plan into the Hudson 401(k) Plan. The Surviving  Corporation may
         at any time after the  Effective  Time modify the Cohoes 401(k) Plan or
         the merged  401(k)  Plans,  as the  Surviving  Corporation  in its sole
         discretion  determines  necessary  or  appropriate  to  accomplish  the
         merger,  and to facilitate  the ongoing  operation of the merged 401(k)
         Plan, subject to compliance with applicable law.

                  (g)  Cohoes  shall,  at the  request of Hudson  terminate  the
         profit  sharing plan  portion of the Cohoes  401(k) Plan at or prior to
         the Closing.

                  (h) The Surviving Corporation shall, as of the Effective Time,
         grant stock options and restricted stock awards to directors (including
         the  emeritus  director)  and  two  executive  officers  of  Cohoes  as
         Previously Disclosed by Hudson.

                  (i) Each  person  who is a director  of Cohoes,  Hudson or its
         respective savings bank Subsidiary,  immediately prior to the Effective
         Time,  who does not become an initial  director of either the Surviving
         Corporation  or  the  Resulting  Institution  at  the  Effective  Time,
         together with Charles  Crotty (if he is an emeritus  director of Cohoes
         immediately prior to the Effective Time) and, at the election of Hudson
         prior to Closing each of its emeritus directors (if such director is an
         emeritus director of Hudson immediately prior to the Effective Time and
         no  alternative  arrangements  have  been  made  by  Hudson  with  such
         director),shall  be  entitled  to become an  emeritus  director  of the
         Surviving  Corporation at the Effective Time as Previously Disclosed by
         Hudson.  Subsequent to the Effective  Time,  each of Carl A. Florio and
         Harry L. Robinson  shall be entitled to become an emeritus  director of
         the Surviving Corporation as Previously Disclosed by Hudson.

                  (j) Prior to the Closing, the Board of Hudson shall approve by
         at least a 75% vote the directors named by the Cohoes Board pursuant to
         Section  2.2(b)(i)  hereof  so as to  ensure  that  completion  of  the
         Transactions  does not  result in a change in  control  under  Hudson's
         change in control severance agreements.

6.12 Bank Merger and Resulting Institution

         The Parties and their respective  savings bank Subsidiaries  shall take
all necessary and appropriate actions to make it possible for the Bank Merger to
be authorized, agreed to, and accomplished immediately after the Effective Time,
or at  such  other  time  thereafter  as may  be  determined  by  the  Surviving
Corporation. In connection with the Bank Merger, the Surviving Corporation shall
cause the following to occur:

                  (a) the name of the Resulting  Institution  shall  continue as

         prior to the Closing. The directors of the Resulting  Institution shall
         be  selected  by the  directors  of the  Surviving  Corporation.  Those
         directors  of  the  Surviving  Corporation   designated  by  pre-Merger
         resolutions of each Party shall, by majority action of such individuals
         and subject to their fiduciary duties, designate one half of the


                                       47

<PAGE>




         directors of the Resulting Institution according to the
         following procedure:

                           (i) Harry L. Robinson and Duncan MacAffer shall be
                  designated by Cohoes to be directors of the Resulting
                  Institution, and Carl A.  Florio and Earl Schram, Jr.
                  shall be designated by Hudson to be directors of the
                  Resulting Institution;

                           (ii)  the   remaining   directors  of  the  Resulting
                  Institution  shall be chosen equally from the Boards of Cohoes
                  and Hudson,  with preference  given to those directors who are
                  not named as directors of the Surviving  Corporation  pursuant
                  to  Section  2.2(b)(i)  hereof  and who do not elect  emeritus
                  director status under Section 6.11(i); and

                           (iii)   Messrs.   MacAffer   and   Schram   shall  be
                  Co-Chairmen of the Board of the Resulting Institution.

         Board of the Surviving  Corporation,  to the extent consistent with its
         fiduciary duties,  shall elect all incumbent directors of the Resulting
         Institution to additional terms. If an incumbent director designated on
         behalf  of  a  Party  is  not  re-elected  or  declines  to  stand  for
         re-election,  then the directors of the Surviving Corporation installed
         by such Party  (inclusive  of any of their  successors in office) shall
         nominate  the  candidate  to be  elected  in  place  of such  incumbent
         director and the Board of Directors of the  Surviving  Corporation,  to
         the extent  consistent  with its  fiduciary  duties,  shall  cause such
         candidate to be elected as a director of the Resulting Institution.  If
         the Board of the Surviving Corporation does not cause such candidate to
         be elected,  then the remaining directors of the Surviving  Corporation
         designated by that Party  (including any of their successors in office)
         shall  choose  another  candidate  until  the  Board  of the  Surviving
         Corporation  causes such  candidate  to be elected as a director of the
         Resulting Institution.

                  (d)  Any  vacancy   among  the   directors  of  the  Resulting
         Institution elected on behalf of a Party pursuant to Section 6.12(b) or
         (c) shall be filled by majority action of those remaining  directors of
         the Resulting Institution who were elected on behalf of such Party.

                  (a) Cohoes  recognizes  that Hudson and its  Subsidiaries  may
         have adopted  different loan,  accrual and reserve policies  (including
         loan  classifications and levels of reserves for possible loan losses).
         Subject  to  applicable  law,  from and  after  the date  hereof to the
         Closing,  Cohoes and Hudson shall consult and cooperate with each other
         with respect to conforming  the loan,  accrual and reserve  policies of
         Cohoes  and its  Subsidiaries  to  those  policies  of  Hudson  and its
         Subsidiaries,  as  specified  in each case in  writing  from  Hudson to
         Cohoes,  based upon such  consultation and subject to the conditions in
         Section 6.14(c) below.

                  (b) Subject to applicable law, Cohoes and Hudson shall consult
         and cooperate with each other with respect to determining, as specified
         in a written notice from Hudson to Cohoes, based upon such consultation
         and subject to the conditions in Section 6.14(c) below,  the amount and
         the timing for recognizing for financial  accounting  purposes  Cohoes'
         expenses of the Transactions and the restructuring  charges relating to
         or to be incurred in connection with the Transactions.

                  (c) Subject to  applicable  law,  Cohoes and its  Subsidiaries
         shall (i) establish and take such reserves and accruals at such time as
         Hudson  shall  reasonably  request to  conform  the loan,  accrual  and
         reserve  policies  of Cohoes and its  Subsidiaries  to the  policies of
         Hudson and its


                                       49

<PAGE>




         Subsidiaries,  and (ii) establish and take such accruals,  reserves and
         charges  in order to  implement  such  policies  and to  recognize  for
         financial  accounting  purposes such expenses of the  Transactions  and
         restructuring  charges  related to or to be incurred in connection with
         the  Transactions,  in  each  case  at  such  times  as are  reasonably
         requested  by  Hudson,  but in no event  prior to five days  before the
         Closing  Date;  provided,  however,  that on the  date  such  reserves,
         accruals and charges are to be taken,  Hudson  shall  certify to Cohoes
         that all conditions to Hudson's obligation to consummate the Merger set
         forth in  Sections  7.1 and 7.3  hereof  (other  than the  delivery  of
         certificates,  opinions  and  other  instruments  and  documents  to be
         delivered  at the  Closing  by  Cohoes,  the  delivery  of which  shall
         continue to be  conditions to Hudson's  obligation  to  consummate  the
         Merger) have been  satisfied or waived;  and  provided,  further,  that
         Cohoes  and its  Subsidiaries  shall not be  required  to take any such
         action  that is not  consistent  with  GAAP and  regulatory  accounting
         principles.

                  (d) No reserves,  accruals or charges taken in accordance with
         this  Section  may be a basis to  assert a  violation  of a breach of a
         representation, warranty or covenant of Cohoes herein.

8.1 Termination

         This Agreement may be terminated by a written  instrument  prior to the
Effective Time:

                  (a) by the mutual consent of the Parties;

                  (b) by the non-breaching Party if the other Party has breached
         in  any  material   respect  any  of  its   covenants,   agreements  or
         representations  and warranties (but in the case of representations and
         warranties  under  Article  IV  subject  to the  standard  set forth in

         after written notice;

                  (c)  by  either  Party,  (i)  if any  Governmental  Entity  of
         competent  jurisdiction shall have issued a final  nonappealable  order

         any  necessary  prior  approval of a  Governmental  Entity is denied or

                                       57

<PAGE>




         withdrawal is not due to the terminating Party's breach of
         any provision of this Agreement;

                  (d) By either Party if the shareholders of either Party do not
         approve the Cohoes Proposal or the Hudson Proposal (including each part
         thereof), as applicable; and

                  (e) by either Party if the Effective  Time has not occurred by
         the  close  of  business  on  February  28,  2001,  provided  that  the
         terminating  Party  is not  then  in  breach  of any of its  covenants,
         agreements  or  representations  and  warranties  (but  in the  case of
         representations and warranties under Article IV subject to the standard

         the breaching  Party from any liability or damages if such  termination

         such event the  non-breaching  Party shall be entitled to such monetary
         remedies and relief  against the  breaching  Party as are  available at
         law; provided,  however,  that the non-breaching Party may only collect
         monetary  damages  against the breaching Party if it shall (i) not have
         exercised any rights under the stock option  agreement  executed by the
         Parties for benefit of the non-breaching Party in the form of Exhibit A
         or B hereto,  whichever is  applicable,  and (ii) cancel and  surrender

that by their  terms are to be  performed  after  the  Effective  Time.  No such
representations,  warranties,  agreements  or  covenants  shall be  deemed to be
terminated or  extinguished  so as to deprive the Surviving  Corporation  or any
affiliate of a Party of any defense at law or in equity which otherwise would be
available against the claims of any person,  including any shareholder or former
shareholder.

8.4 Waiver

         Each  Party  hereto by  written  instrument  approved  by its Board and
signed by an executive officer of such Party, may at any time (whether before or
after approval of this Agreement by the Parties'  shareholders)  extend the time
for the  performance of any of the  obligations or other acts of the other Party
hereto  and  may  waive  (i)  any   inaccuracies  of  the  other  Party  in  the
representations  or  warranties  contained  in this  Agreement  or any  document
delivered   pursuant  hereto,   (ii)  compliance  with  any  of  the  covenants,
undertakings or agreements of the other Party,  (iii) to the extent permitted by
law,  satisfaction  of any  of  the  conditions  precedent  to  its  obligations
contained  herein  or (iv)  the  performance  by the  other  Party of any of its
obligations set forth herein.

8.5 Amendment or Supplement

         This Agreement may be amended at any time by mutual  written  agreement
of the Parties  approved by their Boards and signed by an  executive  officer of
each Party,  provided  that any such  amendment  after the  shareholders  of the
Parties have approved this Agreement  shall not modify either the amount or form
of the Merger  Consideration  or  otherwise  materially  adversely  affect  such
shareholders  without the approval of the shareholders to the extent required by
applicable law.

8.6 Specific Performance

         The Parties  acknowledge and agree that the  Transactions  contemplated
herein  are  unique  and that any  remedy  at law for  breach is  inadequate  to
compensate the aggrieved Party. Accordingly,  each Party shall have the right to
seek specific performance of this Agreement and the other Party's duties,


                                       59

obligations,  covenants and agreements herein in order to cause the Transactions
to be  consummated.  To this end,  each Party,  to the extent  permitted by law,
irrevocably  waives any defense it might have based on the  adequacy of a remedy
at law which might be asserted  as a bar to  specific  performance  or any other
equitable relief.

Hudson, NY 12534


Ladies and Gentlemen:

         Hudson River Bancorp,  Inc.  ("Hudson River") and Cohoes Bancorp,  Inc.
("Cohoes") have entered into an Agreement and Plan of Merger,  dated as of April
25, 2000 (the  "Agreement"),  pursuant  to which  Cohoes will be merged with and
into  Hudson  River  (the  "Merger").  Under  the terms of the  Agreement,  upon
consummation  of the Merger,  each share of Cohoes common stock,  par value $.01
per share, issued and outstanding immediately prior to the effective time of the
Merger  (the  "Cohoes  Shares"),  other than  certain  shares  specified  in the
Agreement,  will be  converted  into the  right to  receive  1.185  shares  (the
"Exchange  Ratio") of Hudson River common stock,  par value $.01 per share.  The
terms and  conditions  of the Merger are more fully set forth in the  Agreement.
You have  requested  our opinion as to the fairness,  from a financial  point of
view,  of the  Exchange  Ratio to the holders of shares of Hudson  River  common
stock.

         Sandler  O'Neill & Partners,  L.P., as part of its  investment  banking
business,  is regularly  engaged in the valuation of financial  institutions and
their securities in connection with mergers and acquisitions and other corporate
transactions.  In connection  with this opinion,  we have reviewed,  among other
things:  (i)  the  Agreement  and  exhibits  thereto;   (ii)  the  Stock  Option
Agreements,  dated as of April 25, 2000, by and between Hudson River and Cohoes;
(iii) certain  publicly  available  financial  statements  and other  historical
financial  information  of Hudson  River that we deemed  relevant;  (iv) certain
publicly  available   financial   statements  and  other  historical   financial
information of Cohoes that we deemed relevant;  (v)consensus  earnings per share
estimates  for Hudson River  published by IBES for the year ending  December 31,
2000 and certain  internal  financial  analyses  and  forecasts  of Hudson River
prepared by and/or  reviewed  with  management  of Hudson River and the views of
senior  management of Hudson River,  based on certain limited  discussions  with
certain  members  of  senior  management,  regarding  Hudson  River's  business,
financial condition,  results of operations and future prospects; (vi) consensus
earnings per share  estimates  for Cohoes  published by IBES for the year ending
December  31,  2000 and  certain  financial  analyses  and  forecasts  of Cohoes
prepared by and/or  reviewed  with  management of Cohoes and the views of senior
management of Cohoes,  based on certain limited discussions with certain members
of senior management,  regarding Cohoes' business,  financial condition, results
of operations and future prospects;  (vii) the pro forma impact of the Merger on
Hudson River; (viii) the publicly reported historical price and trading activity
for Hudson River's and Cohoes' common stock, including a

comparison of certain  financial and stock market  information  for Hudson River
and Cohoes  with  similar  publicly  available  information  for  certain  other
companies the securities of which are publicly traded;  (ix) the financial terms
of recent business  combinations  in the savings  institution  industry,  to the
extent publicly available;  (x) the current market environment generally and the
banking  environment in particular;  and (xi) such other information,  financial
studies, analyses and investigations and financial, economic and market criteria
as we considered relevant.

         In  performing  our  review,  we have  relied  upon  the  accuracy  and
completeness of all of the financial and other information that was available to
us from public  sources,  that was  provided to us by Hudson  River or Cohoes or
their respective  representatives  or that was otherwise reviewed by us and have
assumed such accuracy and  completeness  for purposes of rendering this opinion.
We have not been asked to and have not undertaken an independent verification of
any of such information and we do not assume any responsibility or liability for
the accuracy or completeness thereof. We did not make an independent  evaluation
or appraisal of the  specific  assets,  the  collateral  securing  assets or the
liabilities  (contingent or otherwise) of Hudson River or Cohoes or any of their
subsidiaries,  or the  collectibility  of any  such  assets,  nor  have  we been
furnished  with  any  such  evaluations  or  appraisals.  We  did  not  make  an
independent  evaluation  of the  adequacy  of the  allowance  for loan losses of
Hudson River or Cohoes nor have we reviewed any individual credit files relating
to Hudson River or Cohoes and,  with your  permission,  we have assumed that the
respective  allowances  for loan  losses  for both  Hudson  River and Cohoes are
adequate  to cover such losses and will be adequate on a pro forma basis for the
combined  entity.  We are not  accountants  and have  relied upon the reports of
independent  accountants  for the accuracy  and  completeness  of the  financial
statements  made  available  to us. With  respect to the  financial  projections
prepared by and reviewed  with  management,  we have assumed that they have been
reasonably  prepared on bases reflecting the best currently  available estimates
and judgments of the respective  managements of the respective  future financial
performances  of Hudson  River and  Cohoes  and that such  performances  will be
achieved,  and we express no opinion  as to such  financial  projections  or the
assumptions on which they are based. We have also assumed that there has been no
material  change in Hudson  River's  or  Cohoes'  assets,  financial  condition,
results of operations,  business or prospects  since the date of the most recent
financial  statements  made  available  to us. We have  assumed in all  respects
material  to our  analysis  that  Hudson  River and Cohoes  will remain as going
concerns  for  all  periods   relevant  to  our   analyses,   that  all  of  the
representations  and  warranties  contained  in the  Agreement  and all  related
agreements are true and correct, that each party to such agreements will perform
all of  the  covenants  required  to be  performed  by  such  party  under  such
agreements,  that the  conditions  precedent in the Agreement are not waived and
that the Merger will be accounted for using the purchase method and will qualify
as a tax-free reorganization for federal income tax purposes.

         Our opinion is  necessarily  based on financial,  economic,  market and
other  conditions as in effect on, and the  information  made available to us as
of, the date hereof. Events occurring after the


<PAGE>

Page 3

date hereof could  materially  affect this  opinion.  We have not  undertaken to
update,  revise,  reaffirm or withdraw  this opinion or  otherwise  comment upon
events  occurring after the date hereof.  We are expressing no opinion herein as
to what the value of Hudson  River's common stock will be when issued to Cohoes'
shareholders  pursuant to the Agreement or the prices at which Hudson River's or
Cohoes' common stock will trade at any time.

         We have acted as Hudson River's  financial  advisor in connection  with
the Merger and will receive a fee for our  services,  a  significant  portion of
which is contingent upon consummation of the Merger. We have also received a fee
for rendering this opinion.  In the past, we have also  provided,  and expect to
continue to provide,  certain other investment banking services for Hudson River
and have received, and expect to receive, compensation for such services. In the
ordinary course of our business as a broker-dealer,  we may purchase  securities
from and sell securities to Hudson River and Cohoes.  We may also actively trade
the debt and equity  securities  of Hudson  River and Cohoes for our own account
and for the accounts of our customers and,  accordingly,  may at any time hold a
long or short position in such securities.

         Our opinion is directed to the Board of  Directors  of Hudson  River in
connection  with its  consideration  of the  Merger  and does not  constitute  a
recommendation  to any  shareholder  of Hudson River as to how such  shareholder
should vote at any meeting of shareholders  called to consider and vote upon the
Merger.  Our opinion is not to be quoted or referred to, in whole or in part, in
a registration statement,  prospectus, proxy statement or in any other document,
nor shall this opinion be used for any other purposes, without Sandler O'Neill's
prior  written  consent;  provided,  however,  that  we  hereby  consent  to the
inclusion  of this  opinion as an appendix to Hudson  River's and Cohoes'  Joint
Proxy  Statement/Prospectus  dated the date hereof and to the references to this
opinion therein.

         Based upon and subject to the foregoing,  it is our opinion,  as of the
date hereof, that the Exchange Ratio is fair, from a financial point of view, to
the holders of shares of Hudson River common stock.

                                                Very truly yours,

April 25, 2000


Board of Directors
Cohoes Bancorp, Inc.
75 Remsen Street
Cohoes, New York  12047


Dear  Gentlemen:

You have  requested  our  opinion  as an  independent  investment  banking  firm
regarding the fairness,  from a financial point of view, to the  stockholders of
Cohoes Bancorp,  Inc.  ("Cohoes" or the "Company"),  of the  consideration to be
received by such  stockholders in the merger (the "Merger")  between the Company
and Hudson River Bancorp,  Inc. ("Hudson River").  We have not been requested to
opine as to, and our  opinion  does not in any  manner  address,  the  Company's
underlying business decision to proceed with or effect the Merger.

Pursuant to the Agreement and Plan of Merger, dated April 25, 2000, by and among
the Company and Hudson River (the  "Agreement"),  at the  effective  time of the
Merger,  Hudson River will acquire all of the Company's  issued and  outstanding
shares of common stock.  The holders of the Company's  common stock will receive
in  exchange  for each share of Company  common  stock,  shares of Hudson  River
common  stock based on an exchange  ratio of 1.185 shares of Hudson River common
stock for each share of Cohoes common stock.

In addition,  subject to approval of items 3 and 4, options awarded  pursuant to
the Section  6.11 (h) will  receive  merger  consideration  as described in such
section of the  Agreement.  The complete terms of the proposed  transaction  are
described  in the  Agreement,  and this  summary is qualified in its entirety by
reference thereto.

Keefe,  Bruyette & Woods, Inc., as part of its investment  banking business,  is
regularly  engaged in the  evaluation of businesses and securities in connection
with mergers and acquisitions,  negotiated  underwritings,  and distributions of
listed  and  unlisted  securities.  We are  familiar  with the market for common
stocks of  publicly  traded  banks,  savings  institutions  and bank and savings
institution holding companies.

In connection with this opinion we reviewed certain financial and other business
data  supplied  to us by the Company  including  (i) the  Agreement  and Plan of
Merger by and among Hudson River, Hudson River Bank & Trust Company, Cohoes, and
Cohoes Savings Bank (ii) Annual Reports, Proxy Statements and Form 10-Ks for the
years ended June 30, 1997, 1998 and 1999, (iii) Form 10-Q for the quarters ended

Cohoes Bancorp, Inc.

Page 2


September  30,  1999 and  December  31,  1999 and  other  information  we deemed
relevant. We discussed with senior management and the boards of directors of the
Company  and its wholly  owned  subsidiary,  Cohoes  Savings  Bank,  the current
position and  prospective  outlook for the  Company.  We  considered  historical
quotations and the prices of recorded transactions in the Company's common stock
since its initial public offering.  We reviewed  financial and stock market data
of other savings  institutions,  particularly in the north-eastern region of the
United States,  and the financial and  structural  terms of several other recent
transactions  involving  mergers and  acquisitions  of savings  institutions  or
proposed changes of control of comparably situated companies.

For Hudson River,  we reviewed the audited  financial  statements,  10-K's,  and
Proxy  Statements for the years ended March 31, 1997,  1998, and 1999, Form 10-Q
for the quarters  ended June 30, 1999,  September 30, 1999 and December 31, 1999
and certain other  information  deemed  relevant.  We also discussed with senior
management of Hudson River,  the current  position and  prospective  outlook for
Hudson River.

For purposes of this opinion we have relied,  without independent  verification,
on the accuracy and completeness of the material  furnished to us by the Company
and Hudson  River and the material  otherwise  made  available to us,  including
information from published sources,  and we have not made any independent effort
to verify  such data.  With  respect  to the  financial  information,  including
forecasts and asset  valuations  we received from the Company,  we assumed (with
your  consent)  that  they  had been  reasonably  prepared  reflecting  the best
currently  available  estimates  and judgment of the  Company's  management.  In
addition, we have not made or obtained any independent appraisals or evaluations
of the assets or liabilities, and potential and/or contingent liabilities of the
Company or Hudson River.  We have further relied on the assurances of management
of the Company and Hudson  River that they are not aware of any facts that would
make such information inaccurate or misleading. We express no opinion on matters
of a legal,  regulatory,  tax or accounting nature or the ability of the Merger,
as set forth in the Agreement, to be consummated.

In rendering  our opinion,  we have assumed that in the course of obtaining  the
necessary  approvals  for the Merger,  no  restrictions  or  conditions  will be
imposed that would have a material adverse effect on the  contemplated  benefits
of the  Merger to the  Company or the  ability to  consummate  the  Merger.  Our
opinion is based on the market,  economic and other relevant  considerations  as
they exist and can be evaluated on the date hereof.

Consistent  with the  engagement  letter  with you,  we have acted as  financial
advisor to the Company in connection  with the Merger and will receive a fee for
such services.  In addition,  the Company has agreed to indemnify us for certain
liabilities  arising out of our engagement by the Company in connection with the
Merger.

Based upon and subject to the foregoing, as outlined in the foregoing paragraphs
and based on such other  matters as we  considered  relevant,  it is our opinion
that as of the date hereof, the consideration to be received by the stockholders
of the  Company in the Merger is fair,  from a financial  point of view,  to the
stockholders of the Company.

This  opinion may not,  however,  be  summarized,  excerpted  from or  otherwise
publicly  referred to without our prior written  consent,  although this opinion
may be included in its  entirety in the proxy  statement  of the Company used to
solicit stockholder approval of the Merger. It is understood that this letter is
directed to the Board of  Directors of the Company in its  consideration  of the
Agreement, and is not intended to be and does not constitute a recommendation to
any  stockholder  as to how such  stockholder  should  vote with  respect to the
Merger.

Very truly yours,

BANCORP,  INC., a Delaware  corporation  ("Grantee"),  and HUDSON RIVER BANCORP,
INC., a Delaware corporation ("Issuer").

                              W I T N E S S E T H:

      WHEREAS,  Grantee and Issuer have entered  into an  Agreement  and Plan of
Merger on even date herewith (the "Merger Agreement");

      WHEREAS,  as a condition  and an  inducement  to Grantee to enter into the
Merger Agreement,  Issuer has agreed to grant Grantee the Option (as hereinafter
defined); and

      WHEREAS, the Board of Directors of Issuer has approved the grant
of the Option and the Merger Agreement;

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and in the Merger Agreement,  the parties hereto
agree as follows:

      1. (a)  Issuer  hereby  grants to Grantee  an  unconditional,  irrevocable
option  (the  "Option")  to  purchase,  subject  to the terms  hereof,  up to an
aggregate of 3,093,765 fully paid and nonassessable  shares of the common stock,
par value $.01 per  share,  of Issuer  ("Common  Stock") at a price per share of
$9.3125;  (the "Option Price");  provided,  that in no event shall the number of
shares  for which  this  Option is  exercisable  exceed  19.9% of the issued and
outstanding shares of Common Stock,  without giving effect to any shares subject
to or issued  pursuant to the Option.  The number of shares of Common Stock that
may be received upon the exercise of the Option and the Option Price are subject
to adjustment as herein set forth.

      (b) In the event that any additional  shares of Common Stock are issued or
otherwise  become  outstanding  after  the date of this  Agreement  (other  than
pursuant to this  Agreement  and pursuant to an event  described in Section 5(a)
hereof),  the number of shares of Common  Stock  subject to the Option  shall be
increased so that, after such issuance,  such number together with any shares of
Common Stock previously  issued pursuant  hereto,  equals 19.9% of the number of
shares of Common Stock then issued and outstanding  without giving effect to any
shares  subject or issued  pursuant to the  Option.  Nothing  contained  in this
Section l(b) or elsewhere in this Agreement shall be deemed to authorize  Issuer
to issue shares to others in breach of any provision of the Merger Agreement.

whole  or part,  and  from  time to time,  if,  but  only  if,  both an  Initial
Triggering Event (as hereinafter defined) and a Subsequent  Triggering Event (as
hereinafter  defined) shall have occurred prior to the occurrence of an Exercise
Termination Event (as hereinafter defined),  provided that the Holder shall have

Section 2) within six months following the first Subsequent  Triggering Event to
occur (or such later  period as provided in Section 10).  Each of the  following

the termination was willful (a "Listed Termination"); or (iii) the passage of 12
months (or such longer  period as provided in Section 10) after  termination  of
the Merger  Agreement if such  termination  follows the occurrence of an Initial

Event occurs prior to termination of the Merger  Agreement and continues  beyond
such termination and prior to the passage of such 12-month period, or an Initial
Triggering  Event occurs after a Listed  Termination and prior to the passage of

defined)  but in no event  more  than 18  months  after  such  Merger  Agreement
termination). The "Last Triggering Event" shall mean the last Initial Triggering
Event to  expire.  The term  "Holder"  shall  mean the  holder or holders of the
Option  or  any  portion  thereof.  Notwithstanding  anything  to  the  contrary

available  funds as provided in  subsection  (f) of this Section 2, Issuer shall

purchase the balance of the shares purchasable  hereunder,  and the Holder shall
deliver to Issuer a copy of this Agreement and a letter agreeing that the Holder
will not offer to sell or  otherwise  dispose  of such  shares in  violation  of
applicable law or the provisions of this Agreement.

      (h) Certificates for Common Stock delivered at a closing  hereunder may be
endorsed with a restrictive legend that shall read substantially as follows:

<PAGE>



            "The  transfer  of the shares  represented  by this  certificate  is
      subject to certain  provisions  of an  agreement  between  the  registered
      holder  hereof  and Issuer and to resale  restrictions  arising  under the
      Securities Act of 1933, as amended. A copy of such agreement is on file at
      the  principal  office of Issuer and will be provided to the holder hereof
      without charge upon receipt by Issuer of a written request therefor."

It is understood and agreed that:  (i) the reference to the resale  restrictions
of the Securities Act of 1933, as amended (the  "Securities  Act"), in the above
legend shall be removed by delivery of  substitute  certificate(s)  without such
reference if the Holder  shall have  delivered to Issuer a copy of a letter from
the staff of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory  to Issuer,  to the effect  that such  legend is not  required  for
purposes of the  Securities  Act; (ii) the  reference to the  provisions of this
Agreement  in the above  legend  shall be  removed  by  delivery  of  substitute
certificate(s)   without  such  reference  if  the  shares  have  been  sold  or
transferred  in  compliance  with the  provisions  of this  Agreement  and under
circumstances that do not require the retention of such reference in the opinion
of  counsel  to the  Holder in form and  substance  reasonably  satisfactory  to
Issuer;  and (iii) the legend shall be removed in its entirety if the conditions
in the  preceding  clauses (i) and (ii) are both  satisfied.  In addition,  such
certificates shall bear any other legend as may be required by law.

      (i) Upon the  giving by the  Holder to  Issuer  of the  written  notice of
exercise of the Option provided for under  subsection (e) of this Section 2, the
tender of the applicable  purchase price in immediately  available funds and the
tender of a copy of this  Agreement  to  Issuer,  the  Holder  shall be  deemed,
subject to the receipt of any necessary regulatory  approvals,  to be the holder
of  record  of  the  shares  of  Common  Stock   issuable  upon  such  exercise,
notwithstanding  that the stock transfer books of Issuer shall then be closed or
that  certificates  representing  such shares of Common  Stock shall not then be
actually delivered to the Holder. Issuer shall pay all expenses, and any and all
United  States  federal,  state and local  taxes and other  charges  that may be
payable  in  connection  with  the  preparation,  issue  and  delivery  of stock
certificates  under this  Section 2 in the name of the  Holder or its  assignee,
transferee or designee.

      3.  Issuer  agrees:  (i) that it shall at all  times  maintain,  free from
preemptive  rights,  sufficient  authorized  but unissued or treasury  shares of
Common   Stock  so  that  the  Option  may  be  exercised   without   additional
authorization  of  Common  Stock  after  giving  effect  to all  other  options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,

dissolution or sale of assets,  or by any other  voluntary act, avoid or seek to
avoid the observance or performance  of any of the  covenants,  stipulations  or
conditions to be observed or performed  hereunder by Issuer;  (iii)  promptly to
take  all  action  as may  from  time  to time be  required  (including  without
limitation(x)  complying with all applicable premerger  notification,  reporting
and  waiting  period  requirements  specified  in  15  U.S.C.  Section  18a  and
regulations  promulgated  thereunder  and (y) in the  event,  under any state or
federal  thrift or  banking  law,  prior  approval  of or notice to any state or
federal  regulatory  authority is necessary  before the Option may be exercised,
cooperating  fully with the Holder in preparing such applications or notices and
providing such information to such state or federal regulatory authority as they
may  require)  in order to permit the Holder to  exercise  the Option and Issuer
duly and effectively to issue shares of Common Stock pursuant  hereto;  and (iv)
promptly to take all action  provided herein to protect the rights of the Holder
against dilution.

      4. This  Agreement  (and the  Option  granted  hereby)  are  exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock  purchasable  hereunder.
The terms  "Agreement"  and "Option" as used herein  include any  Agreements and
related  Options for which this Agreement (and the Option granted hereby) may be
exchanged.  Upon receipt by Issuer of evidence reasonably  satisfactory to it of
the loss, theft,  destruction or mutilation of this Agreement,  and (in the case
of loss, theft or destruction) of reasonably satisfactory  indemnification,  and
upon surrender and  cancellation  of this Agreement,  if mutilated,  Issuer will
execute  and  deliver a new  Agreement  of like  tenor  and  date.  Any such new
Agreement  executed and delivered  shall  constitute  an additional  contractual
obligation on the part of Issuer,  whether or not the Agreement so lost, stolen,
destroyed or mutilated shall at any time be enforceable by anyone.

      5. In addition to the  adjustment  in the number of shares of Common Stock
that are  purchasable  upon exercise of the Option pursuant to Section 1 of this
Agreement, the number of shares of Common Stock purchasable upon the exercise of
the Option and the Option Price shall be subject to adjustment from time to time
as provided in this Section 5.

      (a) In the event of any change in Issuer Common Stock by reason of a stock
dividend,  stock split,  split-up,  recapitalization,  combination,  exchange of
shares or  similar  transaction,  the type and  number  of shares or  securities
subject to

                                        7

<PAGE>



the Option shall be adjusted  appropriately,  and proper provision shall be made
in the agreements governing such transaction so that Holder shall receive,  upon
exercise of the Option,  the number and class of shares or other  securities  or
property  that Holder would have  received in respect of Issuer  Common Stock if
the Option had been  exercised  immediately  prior to such event,  or the record
date therefor,  as applicable.  If any additional  shares of Issuer Common Stock
are issued  after the date of this  Agreement  (other than  pursuant to an event
described in the first  sentence of this Section 5(a) or other than  pursuant to
this  Agreement),  the number of shares of Issuer  Common  Stock  subject to the
option  shall be adjusted so that,  after such  issuance,  it together  with any
shares of Issuer Common Stock previously issued pursuant hereto, equals 19.9% of
the number of shares of Issuer Common Stock then issued and outstanding, without
giving effect to any shares subject to or issued pursuant to the Option.

      (b)  Whenever  the  number  of shares of  Common  Stock  purchasable  upon
exercise  hereof is adjusted as  provided  in this  Section 5, the Option  Price
shall be adjusted by multiplying  the Option Price by a fraction,  the numerator
of which  shall be equal to the  number of shares  of Common  Stock  purchasable
prior to the  adjustment  and the  denominator  of  which  shall be equal to the
number of shares of Common Stock purchasable after the adjustment.

      6. Upon the occurrence of a Subsequent  Triggering Event that occurs prior
to an  Exercise  Termination  Event,  Issuer  shall,  at the  request of Grantee
delivered  within six months (or such later period as provided in Section 10) of
such Subsequent  Triggering Event (whether on its own behalf or on behalf of any
subsequent  holder of this  Option  (or part  thereof)  or any of the  shares of
Common Stock issued pursuant hereto),  promptly prepare, file and keep current a
shelf  registration  statement under the Securities Act covering this Option and
any  shares  issued  and  issuable  pursuant  to this  Option  and shall use its
reasonable best efforts to cause such registration statement to become effective
and  remain  current in order to permit  the sale or other  disposition  of this
Option and any shares of Common Stock  issued upon total or partial  exercise of
this  Option  ("Option  Shares")  in  accordance  with any  plan of  disposition
requested by Grantee.  Issuer will use its reasonable best efforts to cause such
registration statement promptly to become effective and then to remain effective
for  such  period  not in  excess  of 6 months  from  the day such  registration
statement  first  becomes  effective or such  shorter time as may be  reasonably
necessary  to effect such sales or other  dispositions.  Grantee  shall have the
right to demand two such  registrations,  provided that any second  registration
shall be requested by Grantee within 12 months (or such later period as provided
in Section 10) following the occurrence of the Subsequent  Triggering Event. The
Issuer shall bear the costs of such registrations (including, but

                                        8

<PAGE>



not limited to, Issuer's attorneys' fees, printing costs and filing fees, except
for  underwriting  discounts  or  commissions,  brokers'  fees  and the fees and
disbursements   of   Grantee's   counsel   related   thereto).   The   foregoing
notwithstanding,  if, at the time of any request by Grantee for  registration of
the Option or Option Shares as provided above,  Issuer is in  registration  with
respect to an underwritten  public offering by Issuer of shares of Common Stock,
and if in the good  faith  judgment  of the  managing  underwriter  or  managing
underwriters,  or,  if  none,  the sole  underwriter  or  underwriters,  of such
offering,  the offer and sale of the  Option  Shares  would  interfere  with the
successful marketing of the shares of Common Stock offered by Issuer, the number
of  Option  Shares  otherwise  to  be  covered  in  the  registration  statement
contemplated  hereby  may be  reduced;  provided,  however,  that after any such
required  reduction  the number of Option Shares to be included in such offering
for the account of all Holders shall constitute at least 25% of the total number
of shares to be sold by the Holders and Issuer in the  aggregate;  and  provided
further,  however,  that if such  reduction  occurs,  then  Issuer  shall file a
registration  statement for the balance as promptly as practicable thereafter as
to which no reduction pursuant to this Section 6 shall be permitted or occur and
the Holder shall  thereafter be entitled to one additional  registration and the
12-month  period  referred to above shall be increased  to 18 months.  Each such
Holder  shall  provide  all  information  reasonably  requested  by  Issuer  for
inclusion in any registration  statement to be filed hereunder.  If requested by
any such Holder in  connection  with such  registration,  Issuer  shall become a
party to any  underwriting  agreement  relating to the sale of such shares,  but
only  to  the  extent  of  obligating  itself  in  respect  of  representations,
warranties,  indemnities  and  other  agreements  customarily  included  in such
underwriting  agreements  for Issuer.  Upon  receiving  any  request  under this
Section 6 from any  Holder,  Issuer  agrees to send a copy  thereof to any other
person known to Issuer to be entitled to registration  rights under this Section
6, in each case by promptly mailing the same, postage prepaid, to the address of
record of the persons entitled to receive such copies.  Notwithstanding anything
to the contrary  contained herein, in no event shall the number of registrations
that Issuer is obligated to effect be increased by reason of the fact that there
shall be more than one Holder as a result of any  assignment or division of this
Agreement.

      7. (a) At any time after the occurrence of a Repurchase  Event (as defined
below)  (i) at the  request  of  the  Holder,  delivered  prior  to an  Exercise
Termination  Event (or such later period as provided in Section 10),  Issuer (or
any successor  thereto)  shall  repurchase the Option from the Holder at a price
(the  "Option   Repurchase  Price")  equal  to  the  amount  by  which  (A)  the
Market/Offer Price (as defined below) exceeds (B) the Option Price,

                                        9

<PAGE>



multiplied  by the number of shares for which this Option may then be  exercised
and (ii) at the  request  of the owner of Option  Shares  from time to time (the
"Owner"), delivered prior to an Exercise Termination Event (or such later period
as provided in Section 10), Issuer (or any successor  thereto) shall  repurchase
such number of the Option Shares from the Owner as the Owner shall  designate at
a price (the "Option Share Repurchase  Price") equal to the  Market/Offer  Price
multiplied by the number of Option Shares so designated.  The term "Market/Offer
Price"  shall  mean the  highest  of (i) the price per share of Common  Stock at
which a tender or  exchange  offer  therefor  has been made,  (ii) the price per
share of Common Stock paid or to be paid by any third party,  other than Grantee
or a  Grantee  Subsidiary,  pursuant  to an  agreement  with  Issuer of the kind
described in Section 2(b)(i) hereof,  (iii) the highest closing price for shares
of Common Stock within the six-month period  immediately  preceding the date the
Holder gives notice of the required repurchase of this Option or the Owner gives
notice of the required  repurchase of Option Shares, as the case may be, or (iv)
in the event of a sale or  transfer of all or any  substantial  part of Issuer's
assets or  deposits,  the sum of the net price paid in such sale for such assets
or deposits and the current  market value of the  remaining net assets of Issuer
as determined by a nationally recognized investment banking firm selected by the
Holder or the Owner,  as the case may be, and  reasonably  acceptable to Issuer,
divided by the  number of shares of Common  Stock of Issuer  outstanding  at the
time of  such  sale.  In  determining  the  Market/Offer  Price,  the  value  of
consideration  other than cash shall be  determined  by a nationally  recognized
investment banking firm selected by the Holder or Owner, as the case may be, and
reasonably acceptable to Issuer.

      (b) The Holder and the Owner,  as the case may be, may  exercise its right
to require  Issuer to repurchase  the Option and any Option  Shares  pursuant to
this  Section 7 by  surrendering  for such purpose to Issuer,  at its  principal
office,  a copy  of  this  Agreement  or  certificates  for  Option  Shares,  as
applicable,  accompanied by a written notice or notices  stating that the Holder
or the Owner,  as the case may be, elects to require  Issuer to repurchase  this
Option  and/or the  Option  Shares in  accordance  with the  provisions  of this
Section 7. The Owner shall also  represent  and warrant  that it has sole record
and  beneficial  ownership of such Option Shares and that such Option Shares are
free and clear of all liens. As promptly as practicable, and in any event within
five  business  days  after the  surrender  of the  Option  and/or  certificates
representing  Option  Shares and the receipt of such notice or notices  relating
thereto,  Issuer shall deliver or cause to be delivered to the Holder the Option
Repurchase  Price and/or to the Owner the Option Share Repurchase Price therefor
or the portion thereof that Issuer is not then prohibited  under  applicable law
and regulation from so delivering.

                                       10

<PAGE>



      (c) To the  extent  that  Issuer is  prohibited  under  applicable  law or
regulation,  or as a consequence of administrative policy, from repurchasing the
Option and/or the Option Shares in full,  Issuer shall immediately so notify the
Holder and/or the Owner and  thereafter  deliver or cause to be delivered,  from
time to time, to the Holder and/or the Owner, as appropriate, the portion of the
Option  Repurchase  Price and the Option Share Repurchase  Price,  respectively,
that it is no longer prohibited from delivering, within five business days after
the date on which Issuer is no longer so prohibited;  provided, however, that if
Issuer  at any  time  after  delivery  of a notice  of  repurchase  pursuant  to
paragraph  (b)  of  this  Section  7  is  prohibited  under  applicable  law  or
regulation,  or as a consequence of  administrative  policy, or as a result of a
written agreement or other binding  obligation with a governmental or regulatory
body or agency,  from delivering to the Holder and/or the Owner, as appropriate,
the Option Repurchase Price and the Option Share Repurchase Price, respectively,
in part or in full (and Issuer  hereby  undertakes  to use its  reasonable  best
efforts to obtain all required  regulatory  and legal  approvals and to file any
required  notices  as  promptly  as  practicable  in  order to  accomplish  such
repurchase),  the Holder or Owner may revoke  its  notice of  repurchase  of the
Option  and/or  the  Option  Shares  either  in  whole or to the  extent  of the
prohibition, whereupon, in the latter case, Issuer shall promptly (i) deliver to
the  Holder  and/or  the  Owner,  as  appropriate,  that  portion  of the Option
Repurchase  Price  and/or the Option Share  Repurchase  Price that Issuer is not
prohibited  from delivering with respect to Options or Option Shares as to which
the Holder or the  Owner,  as the case may be, has not  revoked  its  repurchase
demand; and (ii) deliver, as appropriate,  either (A) to the Holder, a new Stock
Option  Agreement  evidencing the right of the Holder to purchase that number of
shares of Common Stock  obtained by  multiplying  the number of shares of Common
Stock for which the  surrendered  Stock Option  Agreement was exercisable at the
time of delivery of the notice of  repurchase  by a fraction,  the  numerator of
which is the  Option  Repurchase  Price  less the  portion  thereof  theretofore
delivered to the Holder and the  denominator  of which is the Option  Repurchase
Price,  and/or (B) to the Owner, a certificate  for the Option Shares it is then
so prohibited from  repurchasing.  If an Exercise  Termination  Event shall have
occurred  prior to the date of the  notice  by  Issuer  described  in the  first
sentence  of this  subsection  (c), or shall be  scheduled  to occur at any time
before the  expiration  of a period ending on the thirtieth day after such date,
the Holder  shall  nonetheless  have the right to exercise  the Option until the
expiration of such 30-day period.

      (d) For purposes of this Section 7, a  "Repurchase  Event" shall be deemed
to  have  occurred  upon  the  occurrence  of  any of the  following  events  or
transactions after the date hereof:


                                       11

<PAGE>



                  (i) the  acquisition  by any person (other than Grantee or any
      Grantee  Subsidiary)  of  beneficial  ownership of 50% or more of the then
      outstanding Common Stock; or

                  (ii) the consummation of any Acquisition Transaction described
      in Section  2(b)(i)  hereof,  except  that the  percentage  referred to in
      clause (z) shall be 50%.

      8. (a) In the event that prior to an Exercise  Termination  Event,  Issuer
shall enter into an agreement (i) to consolidate  with or merge into any person,
other than Grantee or a Grantee Subsidiary, or engage in a plan of exchange with
any person,  other than Grantee or a Grantee  Subsidiary and Issuer shall not be
the continuing or surviving  corporation of such  consolidation or merger or the
acquirer in such plan of exchange, (ii) to permit any person, other than Grantee
or a Grantee Subsidiary, to merge into Issuer or be acquired by Issuer in a plan
of  exchange  and Issuer  shall be the  continuing  or  surviving  or  acquiring
corporation,  but, in connection with such merger or plan of exchange,  the then
outstanding  shares of Common Stock shall be changed into or exchanged for stock
or other  securities  of any other  person or cash or any other  property or the
then  outstanding  shares of Common  Stock  shall  after such  merger or plan of
exchange represent less than 50% of the outstanding shares and share equivalents
of the merged or acquiring  company,  or (iii) to sell or otherwise transfer all
or a substantial part of its or the Issuer savings bank  Subsidiary's  assets or
deposits to any person, other than Grantee or a Grantee Subsidiary, then, and in
each such case,  the  agreement  governing  such  transaction  shall make proper
provision  so  that  the  Option  shall,  upon  the  consummation  of  any  such
transaction  and upon the terms and  conditions  set forth herein,  be converted
into, or exchanged for, an option (the "Substitute  Option"), at the election of
the Holder, of either (x) the Acquiring  Corporation (as hereinafter defined) or
(y) any person that controls the Acquiring Corporation.

      (b)         The following terms have the meanings indicated:

                  (i) "Acquiring  Corporation"  shall mean (i) the continuing or
      surviving  person of a consolidation  or merger with Issuer (if other than
      Issuer),  (ii) the acquiring  person in a plan of exchange in which Issuer
      is  acquired,  (iii) the Issuer in a merger or plan of  exchange  in which
      Issuer is the  continuing or surviving or acquiring  person,  and (iv) the
      transferee of all or a substantial part of Issuer's assets or deposits (or
      the assets or deposits of the Issuer savings bank Subsidiary).


                                       12

<PAGE>



                  (ii)  "Substitute  Common  Stock"  shall mean the common stock
      issued  by the  issuer  of the  Substitute  Option  upon  exercise  of the
      Substitute Option.

                  (iii) "Assigned Value" shall mean the  Market/Offer  Price, as
      defined in Section 7.

                  (iv) "Average Price" shall mean the average closing price of a
      share of the Substitute  Common Stock for one year  immediately  preceding
      the consolidation,  merger, share exchange or sale in question,  but in no
      event  higher than the closing  price of the shares of  Substitute  Common
      Stock on the day preceding such consolidation,  merger,  share exchange or
      sale;  provided that if Issuer is the issuer of the Substitute Option, the
      Average  Price shall be computed  with  respect to a share of common stock
      issued by the person  merging into Issuer or by any company which controls
      or is controlled by such person, as the Holder may elect.

      (c) The  Substitute  Option  shall  have  the same  terms  as the  Option,
provided that if the terms of the Substitute  Option cannot,  for legal reasons,
be the same as the Option,  such terms shall be as similar as possible and in no
event less advantageous to the Holder. The issuer of the Substitute Option shall
also enter into an agreement  with the then Holder or Holders of the  Substitute
Option in substantially the same form as this Agreement (after giving effect for
such  purpose  to the  provisions  of  Section  9),  which  agreement  shall  be
applicable to the Substitute Option.

      (d) The Substitute  Option shall be exercisable  for such number of shares
of Substitute  Common Stock as is equal to the Assigned Value  multiplied by the
number  of  shares  of  Common  Stock  for  which  the  Option  was  exercisable
immediately  prior to the event described in the first sentence of Section 8(a),
divided by the Average Price.  The exercise  price of the Substitute  Option per
share of  Substitute  Common  Stock  shall  then be equal  to the  Option  Price
multiplied  by a fraction,  the numerator of which shall be the number of shares
of Common Stock for which the Option was  exercisable  immediately  prior to the
event  described in the first  sentence of Section 8(a) and the  denominator  of
which  shall be the number of shares of  Substitute  Common  Stock for which the
Substitute Option is exercisable.

      (e) In no event,  pursuant to any of the foregoing  paragraphs,  shall the
Substitute Option be exercisable for more than 19.9% of the shares of Substitute
Common Stock  outstanding  prior to exercise of the  Substitute  Option.  In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of Substitute Common Stock outstanding prior to exercise but for this

                                       13

<PAGE>



clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash  payment to Holder equal to the excess of (i) the value of the
Substitute  Option  without  giving effect to the  limitation in this clause (e)
over  (ii)  the  value of the  Substitute  Option  after  giving  effect  to the
limitation in this clause (e). This difference in value shall be determined by a
nationally recognized investment banking firm selected by a majority in interest
of the  Holders and the  Owners,  and  reasonably  acceptable  to the  Acquiring
Corporation.

      (f) Issuer shall not enter into any  transaction  described in  subsection
(a) of this  Section 8 unless the  Acquiring  Corporation  and any  person  that
controls the  Acquiring  Corporation  assume in writing all the  obligations  of
Issuer hereunder.

      9.  (a) At the  request  of the  holder  of  the  Substitute  Option  (the
"Substitute  Option Holder"),  the Substitute Option Issuer shall repurchase the
Substitute  Option from the Substitute Option Holder at a price (the "Substitute
Option  Repurchase  Price") equal to the amount by which (i) the Highest Closing
Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute
Option,  multiplied by the number of shares of Substitute Common Stock for which
the  Substitute  Option may then be  exercised,  and at the request of the owner
(the  "Substitute  Share  Owner")  of shares of  Substitute  Common  Stock  (the
"Substitute  Shares"),   the  Substitute  Option  Issuer  shall  repurchase  the
Substitute Shares at a price (the "Substitute Share Repurchase  Price") equal to
the Highest  Closing  Price  multiplied  by the number of  Substitute  Shares so
designated.  The term  "Highest  Closing  Price" shall mean the highest  closing
price for  shares  of  Substitute  Common  Stock  within  the  six-month  period
immediately  preceding the date the Substitute Option Holder gives notice of the
required repurchase of the Substitute Option or the Substitute Share Owner gives
notice of the required repurchase of the Substitute Shares, as applicable.

      (b) Each Substitute  Option Holder and Substitute Share Owner, as the case
may be, may  exercise its  respective  rights to require the  Substitute  Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal  office,  the agreement for such Substitute  Option (or, in the
absence of such an agreement,  a copy of this Agreement) and/or certificates for
Substitute  Shares  accompanied by a written notice or notices  stating that the
Substitute  Option  Holder or the  Substitute  Share Owner,  as the case may be,
elects to require the  Substitute  Option  Issuer to repurchase  the  Substitute
Option and/or the  Substitute  Shares in accordance  with the provisions of this
Section 9. As promptly as practicable and in any event within five business days
after the surrender of the Substitute  Option and/or  certificates  representing
Substitute Shares and the receipt of such

                                       14

<PAGE>



notice or notices relating  thereto,  the Substitute Option Issuer shall deliver
or cause to be delivered to the Substitute  Option Holder the Substitute  Option
Repurchase  Price  and/or to the  Substitute  Share Owner the  Substitute  Share
Repurchase  Price  therefor or, in either case,  the portion  thereof  which the
Substitute  Option  Issuer  is not  then  prohibited  under  applicable  law and
regulation from so delivering.

      (c) To the extent that the  Substitute  Option Issuer is prohibited  under
applicable law or regulation,  or as a consequence of administrative  policy, or
as  a  result  of a  written  agreement  or  other  binding  obligation  with  a
governmental  or regulatory  body or agency,  from  repurchasing  the Substitute
Option and/or the Substitute  Shares in part or in full,  the Substitute  Option
Issuer shall  immediately  so notify the  Substitute  Option  Holder  and/or the
Substitute  Share Owner and  thereafter  deliver or cause to be delivered,  from
time to time, to the Substitute Option Holder and/or the Substitute Share Owner,
as appropriate, the portion of the Substitute Option Repurchase Price and/or the
Substitute  Share  Repurchase  Price,  respectively,   which  it  is  no  longer
prohibited  from  delivering,  within five business days after the date on which
the Substitute Option Issuer is no longer so prohibited; provided, however, that
if the  Substitute  Option  Issuer is at any time after  delivery of a notice of
repurchase  pursuant  to  subsection  (b) of this  Section  9  prohibited  under
applicable law or regulation,  or as a consequence of administrative  policy, or
as  a  result  of a  written  agreement  or  other  binding  obligation  with  a
governmental  or regulatory  body or agency,  from  delivering to the Substitute
Option Holder and/or the Substitute Share Owner, as appropriate,  the Substitute
Option Repurchase Price and the Substitute Share Repurchase Price, respectively,
in full (and the Substitute  Option Issuer shall use its reasonable best efforts
to  receive  all  required   regulatory  and  legal  approvals  as  promptly  as
practicable  in order to accomplish  such  repurchase),  the  Substitute  Option
Holder and/or  Substitute Share Owner may revoke its notice of repurchase of the
Substitute  Option or the Substitute  Shares either in whole or to the extent of
prohibition,  whereupon,  in the latter case, the Substitute Option Issuer shall
promptly (i) deliver to the Substitute  Option Holder or Substitute Share Owner,
as appropriate,  that portion of the Substitute  Option  Repurchase Price or the
Substitute  Share  Repurchase  Price that the  Substitute  Option  Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate,  either (A) to the
Substitute  Option Holder, a new Substitute  Option  evidencing the right of the
Substitute  Option  Holder to purchase  that number of shares of the  Substitute
Common  Stock  obtained by  multiplying  the number of shares of the  Substitute
Common Stock for which the surrendered  Substitute Option was exercisable at the
time of delivery of the notice of  repurchase  by a fraction,  the  numerator of
which is the Substitute Option

                                       15

<PAGE>



Repurchase  Price  less  the  portion  thereof  theretofore   delivered  to  the
Substitute  Option Holder and the denominator of which is the Substitute  Option
Repurchase  Price,  and/or (B) to the Substitute  Share Owner, a certificate for
the Substitute Option Shares it is then so prohibited from  repurchasing.  If an
Exercise  Termination  Event shall have occurred prior to the date of the notice
by the  Substitute  Option  Issuer  described  in the  first  sentence  of  this
subsection (c), or shall be scheduled to occur at any time before the expiration
of a period ending on the thirtieth day after such date, the  Substitute  Option
Holder shall nevertheless have the right to exercise the Substitute Option until
the expiration of such 30-day period.

      10. The 30-day,  6-month,  12-month or  18-month  periods for  exercise of
certain rights under Sections 2, 6, 7 and 9 shall be extended: (i) to the extent
necessary to obtain all  regulatory  approvals  for the exercise of such rights,
and for the expiration of all statutory waiting periods;(ii) during the pendency
of any  temporary  restraining  order,  injunction  or  other  legal  bar to the
exercise of such rights;  and (iii) to the extent  necessary to avoid  liability
under Section 16(b) of the Exchange Act by reason of such exercise.

      11. Issuer hereby represents and warrants to Grantee as follows:

      (a) Issuer has full  corporate  power and authority to execute and deliver
this  Agreement and to consummate  the  transactions  contemplated  hereby.  The
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated  hereby have been duly and validly  authorized by the
Issuer Board on or prior to the date hereof and no other  corporate  proceedings
on the part of Issuer are necessary to authorize this Agreement or to consummate
the  transactions  so  contemplated.  This  Agreement  has been duly and validly
executed and delivered by Issuer.

      (b) Issuer  has taken all  necessary  corporate  action to  authorize  and
reserve and to permit it to issue, and at all times from the date hereof through
the  termination  of this  Agreement  in  accordance  with its  terms  will have
reserved for issuance upon the exercise of the Option,  that number of shares of
Common  Stock equal to the maximum  number of shares of Common Stock at any time
and from time to time  issuable  hereunder,  and all such shares,  upon issuance
pursuant  thereto,  will  be  duly  authorized,   validly  issued,  fully  paid,
nonassessable,  and will be  delivered  free and  clear  of all  claims,  liens,
encumbrance and security interests and not subject to any preemptive rights.

      12. Grantee hereby represents and warrants to Issuer that:


                                       16

<PAGE>



      (a) Grantee has all requisite corporate power and authority to enter into,
execute and deliver this  Agreement  and,  subject to any  approvals or consents
referred to herein,  to consummate the  transactions  contemplated  hereby.  The
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate  action on the part of Grantee and no other  corporate  proceedings on
the part of Grantee are necessary to authorize  this  Agreement or to consummate
the  transactions  so  contemplated.  This  Agreement has been duly executed and
delivered by Grantee.

      (b) The  Option is not  being,  and any  shares  of Common  Stock or other
securities acquired by Grantee upon exercise of the Option will not be, acquired
with a view to the public  distribution  thereof and will not be  transferred or
otherwise  disposed  of  except  in a  transaction  registered  or  exempt  from
registration under the Securities Act.

      13.  Neither  of the  parties  hereto  may  assign  any of its  rights  or
obligations  under this Agreement or the Option  created  hereunder to any other
person,  without the express written consent of the other party,  except that in
the event a Subsequent Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its  rights  and  obligations  hereunder;  within six months
following such Subsequent  Triggering Event;  provided,  however, that until the
date 15 days following the date on which the applicable bank or thrift regulator
has  approved an  application  by Grantee to acquire the shares of Common  Stock
subject to the Option,  but only if such  approval is required,  Grantee may not
assign  its  rights  under the Option  except in (i) a widely  dispersed  public
distribution,  (ii) a private placement in which no one party acquires the right
to purchase in excess of 2% of the voting shares of Issuer,  (iii) an assignment
to a single party (e.g., a broker or investment  banker) for the sole purpose of
conducting a widely  dispersed  public  distribution on Grantee's behalf or (iv)
any other manner approved by the applicable bank or thrift regulator.

      14.  Each of Grantee and Issuer will use its  reasonable  best  efforts to
make all  filings  with,  and to  obtain  consents  of,  all third  parties  and
governmental  authorities  necessary  to the  consummation  of the  transactions
contemplated by this Agreement.

      15. (a) Grantee may, at any time following a Repurchase Event and prior to
the  occurrence  of an  Exercise  Termination  Event  (or such  later  period as
provided in Section 10),  relinquish the Option (together with any Option Shares
issued to and then owned by Grantee) to Issuer in exchange  for a cash fee equal
to the

                                       17

<PAGE>



Surrender Price (as hereinafter  defined);  provided,  however, that Grantee may
not  exercise its rights  pursuant to this Section 15 if Issuer has  repurchased
the Option (or any portion  thereof) or any Option Shares pursuant to Section 7.
The  "Surrender  Price" shall be equal to $4.4 million (i) plus, if  applicable,
Grantee's  purchase  price with respect to any Option Shares and (ii) minus,  if
applicable,  the excess of (A) the net cash amounts, if any, received by Grantee
or a Grantee  Subsidiary  pursuant to the arms' length sale of Option Shares (or
any other  securities into which such Option Shares were converted or exchanged)
to any  unaffiliated  party,  over (B) Grantee's  purchase  price of such Option
Shares.

      (b) Grantee may exercise its right to relinquish the Option and any Option
Shares pursuant to this Section 15 by  surrendering to Issuer,  at its principal
office, a copy of this Agreement  together with  certificates for Option Shares,
if any,  accompanied  by a written  notice  stating (i) that  Grantee  elects to
relinquish  the  Option  and  Option  Shares,  if any,  in  accordance  with the
provisions of this Section 15 and (ii) the Surrender  Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

      (c) To the  extent  that  Issuer is  prohibited  under  applicable  law or
regulation,  or as a consequence of  administrative  policy, or as a result of a
written agreement or other binding  obligation with a governmental or regulatory
body or agency, from paying the Surrender Price to Grantee in full, Issuer shall
immediately so notify  Grantee and thereafter  deliver or cause to be delivered,
from time to time, to Grantee,  the portion of the Surrender Price that it is no
longer prohibited from paying, within five business days after the date on which
Issuer is no longer so prohibited; provided, however, that if Issuer at any time
after  delivery  of a notice of  surrender  pursuant  to  paragraph  (b) of this
Section 15 is prohibited under applicable law or regulation, or as a consequence
of administrative policy, or as a result of a written agreement or other binding
obligation  with a  governmental  or regulatory  body or agency,  from paying to
Grantee the  Surrender  Price in full,  (i) Issuer shall (A) use its  reasonable
best efforts to obtain all required  regulatory and legal  approvals and to file
any required  notices as promptly as practicable in order to make such payments,
(B) within five days of the  submission or receipt of any documents  relating to
any such  regulatory  and legal  approvals,  provide  Grantee with copies of the
same,  and (c) keep  Grantee  advised of both the status of any such request for
regulatory and legal  approvals,  as well as any  discussions  with any relevant
regulatory or other third party reasonably  related to the same and (ii) Grantee
may revoke such notice of  surrender  by delivery of a notice of  revocation  to
Issuer and, upon delivery of such notice of

                                       18

<PAGE>



revocation,  the  Exercise  Termination  Event  shall be  extended to a date six
months from the date on which the Exercise Termination Event would have occurred
if not for the provisions of this Section 15(c) (during which period Grantee may
exercise any of its rights  hereunder,  including any and all rights pursuant to
this Section 15).

      16. The parties  hereto  acknowledge  that damages  would be an inadequate
remedy  for a breach of this  Agreement  by  either  party  hereto  and that the
obligations  of the parties  hereto shall be  enforceable by either party hereto
through  injunctive or other  equitable  relief.  In connection  therewith  both
parties waive the posting of any bond or similar requirement.

      17. If any term,  provision,  covenant or  restriction  contained  in this
Agreement  is held  by a court  or a  federal  or  state  regulatory  agency  of
competent  jurisdiction to be invalid,  void or unenforceable,  the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or  invalidated.  If for any reason such court or regulatory  agency  determines
that the Holder is not  permitted  to acquire,  or Issuer or  Substitute  Option
Issuer, as the case may be, is not permitted to repurchase  pursuant to Sections
7 or 9, as the case may be, the full number of shares of Common  Stock  provided
in  Section  l(a)  hereof (as  adjusted  pursuant  to Section  l(b) or Section 5
hereof),  it is the  express  intention  of Issuer  (which  shall be  binding on
Substitute Option Issuer) to allow the Holder to acquire or to require Issuer or
Substitute  Option Issuer,  as the case may be, to repurchase such lesser number
of shares as may be permissible, without any amendment or modification hereof.

      18.  All  notices,  requests,  claims,  demands  and other  communications
hereunder  shall be deemed to have been duly given when delivered in person,  by
fax,  telecopy,  or by registered or certified  mail  (postage  prepaid,  return
receipt  requested) at the respective  addresses of the parties set forth in the
Merger Agreement.

      19. This Agreement  shall be governed by and construed in accordance  with
the  laws of the  State of  Delaware,  without  regard  to the  conflict  of law
principles  thereof  (except to the extent that mandatory  provisions of Federal
law are applicable).

      20. This  Agreement may be executed in two or more  counterparts,  each of
which shall be deemed to be an original,  but all of which shall  constitute one
and the same agreement.

      21. Except as otherwise  expressly  provided  herein,  each of the parties
hereto shall bear and pay all costs and expenses

                                       19

<PAGE>



incurred by it or on its behalf in connection with the transactions contemplated
hereunder,  including  fees  and  expenses  of its  own  financial  consultants,
investment bankers, accountants and counsel.

      22.  Except  as  otherwise  expressly  provided  herein  or in the  Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the  transactions  contemplated  hereunder and  supersedes  all prior
arrangements or understandings with respect thereof,  written or oral. The terms
and  conditions of this  Agreement  shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assignees.
Nothing in this Agreement,  expressed or implied, is intended to confer upon any
party,  other than the  parties  hereto,  and their  respective  successors  and
permitted assignees, any rights,  remedies,  obligations or liabilities under or
by reason of this Agreement, except as expressly provided herein.

      23.  Capitalized terms used in this Agreement and not defined herein shall
have the meanings assigned thereto in the Merger Agreement.

      IN WITNESS  WHEREOF,  each of the parties has caused this  Agreement to be
executed on its behalf by its officers thereunto duly authorized,  all as of the
date first above written.

                             STOCK OPTION AGREEMENT

      STOCK OPTION AGREEMENT,  dated as of April 25, 2000,  between HUDSON RIVER
BANCORP, INC., a Delaware corporation  ("Grantee"),  and COHOES BANCORP, INC., a
Delaware corporation ("Issuer").

                              W I T N E S S E T H:

      WHEREAS,  Grantee and Issuer have entered  into an  Agreement  and Plan of
Merger on even date herewith (the "Merger Agreement");

      WHEREAS,  as a condition  and an  inducement  to Grantee to enter into the
Merger Agreement,  Issuer has agreed to grant Grantee the Option (as hereinafter
defined); and

      WHEREAS, the Board of Directors of Issuer has approved the grant
of the Option and the Merger Agreement;

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and in the Merger Agreement,  the parties hereto
agree as follows:

      1. (a)  Issuer  hereby  grants to Grantee  an  unconditional,  irrevocable
option  (the  "Option")  to  purchase,  subject  to the terms  hereof,  up to an
aggregate of 1,574,538 fully paid and nonassessable  shares of the common stock,
par value $.01 per  share,  of Issuer  ("Common  Stock") at a price per share of
$9.8125(the  "Option  Price");  provided,  that in no event  shall the number of
shares  for which  this  Option is  exercisable  exceed  19.9% of the issued and
outstanding shares of Common Stock,  without giving effect to any shares subject
to or issued  pursuant to the Option.  The number of shares of Common Stock that
may be received upon the exercise of the Option and the Option Price are subject
to adjustment as herein set forth.

      (b) In the event that any additional  shares of Common Stock are issued or
otherwise  become  outstanding  after  the date of this  Agreement  (other  than
pursuant to this  Agreement  and pursuant to an event  described in Section 5(a)
hereof),  the number of shares of Common  Stock  subject to the Option  shall be
increased so that, after such issuance,  such number together with any shares of
Common Stock previously  issued pursuant  hereto,  equals 19.9% of the number of
shares of Common Stock then issued and outstanding  without giving effect to any
shares  subject or issued  pursuant to the  Option.  Nothing  contained  in this
Section l(b) or elsewhere in this Agreement shall be deemed to authorize  Issuer
to issue shares to others in breach of any provision of the Merger Agreement.

      2. (a) The Holder (as  hereinafter  defined) may  exercise the Option,  in
whole or part, and from time to time, if, but only if,

                                        1

<PAGE>



both an Initial  Triggering  Event (as  hereinafter  defined)  and a  Subsequent
Triggering  Event (as  hereinafter  defined)  shall have  occurred  prior to the
occurrence of an Exercise Termination Event (as hereinafter  defined),  provided
that the Holder shall have sent the written notice of such exercise (as provided
in  subsection  (e) of this  Section 2) within six  months  following  the first
Subsequent  Triggering  Event to occur  (or such  later  period as  provided  in
Section 10). Each of the following shall be an Exercise  Termination  Event: (i)
the Effective Time (as defined in the Merger Agreement); (ii) termination of the
Merger  Agreement in accordance with the provisions  thereof if such termination
occurs  prior  to the  occurrence  of an  Initial  Triggering  Event,  except  a
termination by Grantee  pursuant to Section 8.1(b) of the Merger Agreement where
the  breach by Issuer  giving  rise to the  termination  was  willful (a "Listed
Termination");  or (iii) the  passage  of 12 months  (or such  longer  period as
provided  in  Section  10) after  termination  of the Merger  Agreement  if such
termination  follows the occurrence of an Initial  Triggering  Event or a Listed
Termination  (provided  that if an  Initial  Triggering  Event  occurs  prior to
termination of the Merger  Agreement and continues  beyond such  termination and
prior to the passage of such 12-month  period,  or an Initial  Triggering  Event
occurs  after a Listed  Termination  and prior to the  passage  of such 12 month
period,  then in either case the Exercise  Termination  Event shall be 12 months
from the expiration of the Last Triggering Event (as hereinafter defined) but in
no event more than 18 months after such Merger Agreement termination). The "Last
Triggering  Event" shall mean the last Initial  Triggering Event to expire.  The
term  "Holder"  shall mean the  holder or  holders of the Option or any  portion
thereof.  Notwithstanding  anything to the contrary contained herein, the Option
may not be exercised at any time when Grantee shall be in willful  breach of the
Merger  Agreement  such that Issuer  shall be entitled to  terminate  the Merger
Agreement  pursuant  to  Section  8.1(b)  thereof  as a result of such a willful
breach.

      (b) The term  "Initial  Triggering  Event" shall mean any of the following
events or transactions occurring on or after the date hereof:

                  (i) Issuer or any of its Significant  Subsidiaries (as defined
      in Rule 1-02 of Regulation S-X  promulgated by the Securities and Exchange
      Commission (the "SEC")) (an "Issuer Subsidiary"),  without having received
      Grantee's prior written  consent,  shall have entered into an agreement to
      engage in an Acquisition  Transaction  (as  hereinafter  defined) with any
      person  (the term  "person"  for  purposes  of this  Agreement  having the
      meaning   assigned  thereto  in  Sections  3(a)(9)  and  13(d)(3)  of  the
      Securities  Exchange Act of 1934, as amended (the "Exchange Act"), and the
      rules and regulations thereunder) other than

                                        2

<PAGE>



      Grantee or any of its  Subsidiaries  (each a "Grantee  Subsidiary") or the
      Board of Directors of Issuer (the "Issuer  Board") shall have  recommended
      that  the  shareholders  of  Issuer  approve  or  accept  any  Acquisition
      Transaction  with any person other than  Grantee or a Grantee  Subsidiary.
      For purposes of this Agreement,  (a) "Acquisition  Transaction" shall mean
      (x) a merger  or  consolidation,  or any  similar  transaction,  involving
      Issuer or any Issuer  Subsidiary  (other than mergers,  consolidations  or
      similar  transactions  (i)  involving  solely  Issuer  and/or  one or more
      wholly-owned Subsidiaries of the Issuer, provided, any such transaction is
      not entered  into in violation  of the terms of the Merger  Agreement)  or
      (ii) in which  shareholders of Issuer  immediately  prior to completion of
      such  transaction  own at least 50% of the common  stock of Issuer (or the
      resulting or surviving  entity in such  transaction),  provided,  any such
      transaction  is not entered  into in  violation of the terms of the Merger
      Agreement),  (y) a purchase,  lease or other  acquisition or assumption of
      all or any  substantial  part of the assets or  deposits  of Issuer or any
      Issuer  Subsidiary,  or (z) a purchase or other acquisition  (including by
      way of merger,  consolidation,  share exchange or otherwise) of securities
      representing  10% or more of the  voting  power of  Issuer  or any  Issuer
      Subsidiary and (b) "Grantee Subsidiary" shall mean a subsidiary of Grantee
      within the definition set forth in Rule 12b-2 under the Exchange Act;

                  (ii)  Any  person,  other  than  the  Grantee  or any  Grantee
      Subsidiary,  shall  have  acquired  beneficial  ownership  or the right to
      acquire  beneficial  ownership of 10% or more of the outstanding shares of
      Common  Stock  (the  term  "beneficial  ownership"  for  purposes  of this
      Agreement  having the  meaning  assigned  thereto in Section  13(d) of the
      Exchange Act, and the rules and regulations thereunder);

                  (iii) It shall have been  publicly  announced  that any person
      (other than Grantee or a Grantee  Subsidiary) shall have made, or publicly
      disclosed  an  intention  to make,  a bona fide  proposal  to engage in an
      Acquisition Transaction;

                  (iv) (x) The Issuer Board,  without having received  Grantee's
      prior  written  consent,  shall have  withdrawn  or modified  (or publicly
      announced  its  intention to withdraw or modify) in any manner  adverse in
      any respect to Grantee its recommendation  that the shareholders of Issuer
      approve the transactions  contemplated by the Merger Agreement, (y) Issuer
      or any Issuer Subsidiary,  without having received Grantee's prior written
      consent,  shall  have  authorized,   recommended,  proposed  (or  publicly
      announced its  intention to authorize,  recommend or propose) an agreement
      to engage in an Acquisition

                                        3

<PAGE>



      Transaction with any person other than Grantee or a Grantee  Subsidiary or
      (z) Issuer shall have provided  information to or engaged in  negotiations
      with a third party relating to a possible Acquisition Transaction.

                  (v) Any person,  other than Grantee or any Grantee Subsidiary,
      shall have filed with the SEC a  registration  statement  or tender  offer
      materials with respect to a potential  exchange or tender offer that would
      constitute  an  Acquisition  Transaction  (or  filed a  preliminary  proxy
      statement   with  the  SEC  with  respect  to  a  potential  vote  by  its
      shareholders  to approve  the  issuance of shares to be offered in such an
      exchange offer);

                  (vi) Issuer  shall have  willfully  breached  any  covenant or
      obligation  contained in the Merger Agreement after an overture is made by
      a third party to Issuer or its  shareholders  to engage in an  Acquisition
      Transaction,  and such breach (y) would  entitle  Grantee to terminate the
      Merger  Agreement  (whether  immediately  or after the giving of notice or
      passage  of time or both) and (z) shall not have been  cured  prior to the
      Notice Date (as defined below); or

                  (vii) Any person, other than Grantee or any Grantee Subsidiary
      and other than in connection with a transaction to which Grantee has given
      its prior written consent,  shall have filed an application or notice with
      any federal or state thrift or bank  regulatory  or  antitrust  authority,
      which application or notice has been accepted for processing, for approval
      to engage in an Acquisition Transaction.

      (c) The term "Subsequent Triggering Event" shall mean any of the following
events or transactions occurring after the date hereof:

                  (i) The  acquisition  by any person (other than Grantee or any
      Grantee  Subsidiary)  of  beneficial  ownership of 25% or more of the then
      outstanding Common Stock; or

                  (ii) The occurrence of an Initial  Triggering  Event described
      in  clause  (i) of  subsection  (b) of this  Section  2,  except  that the
      percentage  referred to in clause (z) of the second sentence thereof shall
      be 25%.

      (d) Issuer shall notify  Grantee  promptly in writing of the occurrence of
any  Initial  Triggering  Event or  Subsequent  Triggering  Event  (together,  a
"Triggering  Event"),  it being  understood  that the  giving of such  notice by
Issuer  shall not be a  condition  to the right of the  Holder to  exercise  the
Option.


                                        4

<PAGE>



      (e) In the event the  Holder is  entitled  to and wishes to  exercise  the
Option (or any portion  thereof),  it shall send to Issuer a written notice (the
date of which being herein referred to as the "Notice Date")  specifying (i) the
total  number of shares it will  purchase  pursuant to such  exercise and (ii) a
place and date not earlier than three  business  days nor later than 60 business
days from the Notice Date for the closing of such purchase (the "Closing Date");
provided,  that if  prior  notification  to or  approval  of any  regulatory  or
antitrust agency is required in connection with such purchase,  the Holder shall
promptly file the required  notice or application  for approval,  shall promptly
notify  Issuer of such filing and shall  expeditiously  process the same and the
period of time that  otherwise  would run  pursuant to this  sentence  shall run
instead from the date on which any required notification periods have expired or
been  terminated or such approvals have been obtained and any requisite  waiting
period or periods shall have passed.  Any exercise of the Option shall be deemed
to occur on the  Notice  Date  relating  thereto.  The term  "business  day" for
purposes of this Agreement means any day, excluding  Saturdays,  Sundays and any
other  day that is a legal  holiday  in the  State of New York or a day on which
banking institutions in the State of New York are authorized by law or executive
order to close.

      (f) At the closing  referred to in  subsection  (e) of this Section 2, the
Holder shall (i) pay to Issuer the  aggregate  purchase  price for the shares of
Common Stock  purchased  pursuant to the  exercise of the Option in  immediately
available funds by wire transfer to a bank account designated by Issuer and (ii)
present  and  surrender  this  Agreement  to Issuer at its  principal  executive
offices,  provided that the failure or refusal of the Issuer to designate such a
bank account or accept surrender of this Agreement shall not preclude the Holder
from exercising the Option.

      (g) At such  closing,  simultaneously  with the  delivery  of  immediately
available  funds as provided in  subsection  (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates  representing  the number of
shares of Common  Stock  purchased by the Holder and, if the Option is exercised
in part only,  a new  Option  evidencing  the  rights of the  Holder  thereof to
purchase the balance of the shares purchasable  hereunder,  and the Holder shall
deliver to Issuer a copy of this Agreement and a letter agreeing that the Holder
will not offer to sell or  otherwise  dispose  of such  shares in  violation  of
applicable law or the provisions of this Agreement.

      (h) Certificates for Common Stock delivered at a closing  hereunder may be
endorsed with a restrictive legend that shall read substantially as follows:

<PAGE>



            "The  transfer  of the shares  represented  by this  certificate  is
      subject to certain  provisions  of an  agreement  between  the  registered
      holder  hereof  and Issuer and to resale  restrictions  arising  under the
      Securities Act of 1933, as amended. A copy of such agreement is on file at
      the  principal  office of Issuer and will be provided to the holder hereof
      without charge upon receipt by Issuer of a written request therefor."

It is understood and agreed that:  (i) the reference to the resale  restrictions
of the Securities Act of 1933, as amended (the  "Securities  Act"), in the above
legend shall be removed by delivery of  substitute  certificate(s)  without such
reference if the Holder  shall have  delivered to Issuer a copy of a letter from
the staff of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory  to Issuer,  to the effect  that such  legend is not  required  for
purposes of the  Securities  Act; (ii) the  reference to the  provisions of this
Agreement  in the above  legend  shall be  removed  by  delivery  of  substitute
certificate(s)   without  such  reference  if  the  shares  have  been  sold  or
transferred  in  compliance  with the  provisions  of this  Agreement  and under
circumstances that do not require the retention of such reference in the opinion
of  counsel  to the  Holder in form and  substance  reasonably  satisfactory  to
Issuer;  and (iii) the legend shall be removed in its entirety if the conditions
in the  preceding  clauses (i) and (ii) are both  satisfied.  In addition,  such
certificates shall bear any other legend as may be required by law.

      (i) Upon the  giving by the  Holder to  Issuer  of the  written  notice of
exercise of the Option provided for under  subsection (e) of this Section 2, the
tender of the applicable  purchase price in immediately  available funds and the
tender of a copy of this  Agreement  to  Issuer,  the  Holder  shall be  deemed,
subject to the receipt of any necessary regulatory  approvals,  to be the holder
of  record  of  the  shares  of  Common  Stock   issuable  upon  such  exercise,
notwithstanding  that the stock transfer books of Issuer shall then be closed or
that  certificates  representing  such shares of Common  Stock shall not then be
actually delivered to the Holder. Issuer shall pay all expenses, and any and all
United  States  federal,  state and local  taxes and other  charges  that may be
payable  in  connection  with  the  preparation,  issue  and  delivery  of stock
certificates  under this  Section 2 in the name of the  Holder or its  assignee,
transferee or designee.

      3.  Issuer  agrees:  (i) that it shall at all  times  maintain,  free from
preemptive  rights,  sufficient  authorized  but unissued or treasury  shares of
Common   Stock  so  that  the  Option  may  be  exercised   without   additional
authorization  of  Common  Stock  after  giving  effect  to all  other  options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,
merger,

                                        6

<PAGE>



dissolution or sale of assets,  or by any other  voluntary act, avoid or seek to
avoid the observance or performance  of any of the  covenants,  stipulations  or
conditions to be observed or performed  hereunder by Issuer;  (iii)  promptly to
take  all  action  as may  from  time  to time be  required  (including  without
limitation (x) complying with all applicable premerger  notification,  reporting
and  waiting  period  requirements  specified  in  15  U.S.C.  Section  18a  and
regulations  promulgated  thereunder  and (y) in the  event,  under any state or
federal  thrift or  banking  law,  prior  approval  of or notice to any state or
federal  regulatory  authority is necessary  before the Option may be exercised,
cooperating  fully with the Holder in preparing such applications or notices and
providing such information to such state or federal regulatory authority as they
may  require)  in order to permit the Holder to  exercise  the Option and Issuer
duly and effectively to issue shares of Common Stock pursuant  hereto;  and (iv)
promptly to take all action  provided herein to protect the rights of the Holder
against dilution.

      4. This  Agreement  (and the  Option  granted  hereby)  are  exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock  purchasable  hereunder.
The terms  "Agreement"  and "Option" as used herein  include any  Agreements and
related  Options for which this Agreement (and the Option granted hereby) may be
exchanged.  Upon receipt by Issuer of evidence reasonably  satisfactory to it of
the loss, theft,  destruction or mutilation of this Agreement,  and (in the case
of loss, theft or destruction) of reasonably satisfactory  indemnification,  and
upon surrender and  cancellation  of this Agreement,  if mutilated,  Issuer will
execute  and  deliver a new  Agreement  of like  tenor  and  date.  Any such new
Agreement  executed and delivered  shall  constitute  an additional  contractual
obligation on the part of Issuer,  whether or not the Agreement so lost, stolen,
destroyed or mutilated shall at any time be enforceable by anyone.

      5. In addition to the  adjustment  in the number of shares of Common Stock
that are  purchasable  upon exercise of the Option pursuant to Section 1 of this
Agreement, the number of shares of Common Stock purchasable upon the exercise of
the Option and the Option Price shall be subject to adjustment from time to time
as provided in this Section 5.

      (a) In the event of any change in Issuer Common Stock by reason of a stock
dividend,  stock split,  split-up,  recapitalization,  combination,  exchange of
shares or  similar  transaction,  the type and  number  of shares or  securities
subject to

                                        7

<PAGE>



the Option shall be adjusted  appropriately,  and proper provision shall be made
in the agreements governing such transaction so that Holder shall receive,  upon
exercise of the Option,  the number and class of shares or other  securities  or
property  that Holder would have  received in respect of Issuer  Common Stock if
the Option had been  exercised  immediately  prior to such event,  or the record
date therefor,  as applicable.  If any additional  shares of Issuer Common Stock
are issued  after the date of this  Agreement  (other than  pursuant to an event
described in the first  sentence of this Section 5(a) or other than  pursuant to
this  Agreement),  the number of shares of Issuer  Common  Stock  subject to the
option  shall be adjusted so that,  after such  issuance,  it together  with any
shares of Issuer Common Stock previously issued pursuant hereto, equals 19.9% of
the number of shares of Issuer Common Stock then issued and outstanding, without
giving effect to any shares subject to or issued pursuant to the Option.

      (b)  Whenever  the  number  of shares of  Common  Stock  purchasable  upon
exercise  hereof is adjusted as  provided  in this  Section 5, the Option  Price
shall be adjusted by multiplying  the Option Price by a fraction,  the numerator
of which  shall be equal to the  number of shares  of Common  Stock  purchasable
prior to the  adjustment  and the  denominator  of  which  shall be equal to the
number of shares of Common Stock purchasable after the adjustment.

      6. Upon the occurrence of a Subsequent  Triggering Event that occurs prior
to an  Exercise  Termination  Event,  Issuer  shall,  at the  request of Grantee
delivered  within six months (or such later period as provided in Section 10) of
such Subsequent  Triggering Event (whether on its own behalf or on behalf of any
subsequent  holder of this  Option  (or part  thereof)  or any of the  shares of
Common Stock issued pursuant hereto),  promptly prepare, file and keep current a
shelf  registration  statement under the Securities Act covering this Option and
any  shares  issued  and  issuable  pursuant  to this  Option  and shall use its
reasonable best efforts to cause such registration statement to become effective
and  remain  current in order to permit  the sale or other  disposition  of this
Option and any shares of Common Stock  issued upon total or partial  exercise of
this  Option  ("Option  Shares")  in  accordance  with any  plan of  disposition
requested by Grantee.  Issuer will use its reasonable best efforts to cause such
registration statement promptly to become effective and then to remain effective
for  such  period  not in  excess  of 6 months  from  the day such  registration
statement  first  becomes  effective or such  shorter time as may be  reasonably
necessary  to effect such sales or other  dispositions.  Grantee  shall have the
right to demand two such  registrations,  provided that any second  registration
shall be requested by Grantee within 12 months (or such later period as provided
in Section 10) following the occurrence of the Subsequent  Triggering Event. The
Issuer shall bear the costs of such registrations (including, but

                                        8

<PAGE>



not limited to, Issuer's attorneys' fees, printing costs and filing fees, except
for  underwriting  discounts  or  commissions,  brokers'  fees  and the fees and
disbursements   of   Grantee's   counsel   related   thereto).   The   foregoing
notwithstanding,  if, at the time of any request by Grantee for  registration of
the Option or Option Shares as provided above,  Issuer is in  registration  with
respect to an underwritten  public offering by Issuer of shares of Common Stock,
and if in the good  faith  judgment  of the  managing  underwriter  or  managing
underwriters,  or,  if  none,  the sole  underwriter  or  underwriters,  of such
offering,  the offer and sale of the  Option  Shares  would  interfere  with the
successful marketing of the shares of Common Stock offered by Issuer, the number
of  Option  Shares  otherwise  to  be  covered  in  the  registration  statement
contemplated  hereby  may be  reduced;  provided,  however,  that after any such
required  reduction  the number of Option Shares to be included in such offering
for the account of all Holders shall constitute at least 25% of the total number
of shares to be sold by the Holders and Issuer in the  aggregate;  and  provided
further,  however,  that if such  reduction  occurs,  then  Issuer  shall file a
registration  statement for the balance as promptly as practicable thereafter as
to which no reduction pursuant to this Section 6 shall be permitted or occur and
the Holder shall  thereafter be entitled to one additional  registration and the
12-month  period  referred to above shall be increased  to 18 months.  Each such
Holder  shall  provide  all  information  reasonably  requested  by  Issuer  for
inclusion in any registration  statement to be filed hereunder.  If requested by
any such Holder in  connection  with such  registration,  Issuer  shall become a
party to any  underwriting  agreement  relating to the sale of such shares,  but
only  to  the  extent  of  obligating  itself  in  respect  of  representations,
warranties,  indemnities  and  other  agreements  customarily  included  in such
underwriting  agreements  for Issuer.  Upon  receiving  any  request  under this
Section 6 from any  Holder,  Issuer  agrees to send a copy  thereof to any other
person known to Issuer to be entitled to registration  rights under this Section
6, in each case by promptly mailing the same, postage prepaid, to the address of
record of the persons entitled to receive such copies.  Notwithstanding anything
to the contrary  contained herein, in no event shall the number of registrations
that Issuer is obligated to effect be increased by reason of the fact that there
shall be more than one Holder as a result of any  assignment or division of this
Agreement.

      7. (a) At any time after the occurrence of a Repurchase  Event (as defined
below)  (i) at the  request  of  the  Holder,  delivered  prior  to an  Exercise
Termination  Event (or such later period as provided in Section 10),  Issuer (or
any successor  thereto)  shall  repurchase the Option from the Holder at a price
(the  "Option   Repurchase  Price")  equal  to  the  amount  by  which  (A)  the
Market/Offer Price (as defined below) exceeds (B) the Option Price,

                                        9

<PAGE>



multiplied  by the number of shares for which this Option may then be  exercised
and (ii) at the  request  of the owner of Option  Shares  from time to time (the
"Owner"), delivered prior to an Exercise Termination Event (or such later period
as provided in Section 10), Issuer (or any successor  thereto) shall  repurchase
such number of the Option Shares from the Owner as the Owner shall  designate at
a price (the "Option Share Repurchase  Price") equal to the  Market/Offer  Price
multiplied by the number of Option Shares so designated.  The term "Market/Offer
Price"  shall  mean the  highest  of (i) the price per share of Common  Stock at
which a tender or  exchange  offer  therefor  has been made,  (ii) the price per
share of Common Stock paid or to be paid by any third party,  other than Grantee
or a  Grantee  Subsidiary,  pursuant  to an  agreement  with  Issuer of the kind
described in Section 2(b)(i) hereof,  (iii) the highest closing price for shares
of Common Stock within the six-month period  immediately  preceding the date the
Holder gives notice of the required repurchase of this Option or the Owner gives
notice of the required  repurchase of Option Shares, as the case may be, or (iv)
in the event of a sale or  transfer of all or any  substantial  part of Issuer's
assets or  deposits,  the sum of the net price paid in such sale for such assets
or deposits and the current  market value of the  remaining net assets of Issuer
as determined by a nationally recognized investment banking firm selected by the
Holder or the Owner,  as the case may be, and  reasonably  acceptable to Issuer,
divided by the  number of shares of Common  Stock of Issuer  outstanding  at the
time of  such  sale.  In  determining  the  Market/Offer  Price,  the  value  of
consideration  other than cash shall be  determined  by a nationally  recognized
investment banking firm selected by the Holder or Owner, as the case may be, and
reasonably acceptable to Issuer.

      (b) The Holder and the Owner,  as the case may be, may  exercise its right
to require  Issuer to repurchase  the Option and any Option  Shares  pursuant to
this  Section 7 by  surrendering  for such purpose to Issuer,  at its  principal
office,  a copy  of  this  Agreement  or  certificates  for  Option  Shares,  as
applicable,  accompanied by a written notice or notices  stating that the Holder
or the Owner,  as the case may be, elects to require  Issuer to repurchase  this
Option  and/or the  Option  Shares in  accordance  with the  provisions  of this
Section 7. The Owner shall also  represent  and warrant  that it has sole record
and  beneficial  ownership of such Option Shares and that such Option Shares are
free and clear of all liens. As promptly as practicable, and in any event within
five  business  days  after the  surrender  of the  Option  and/or  certificates
representing  Option  Shares and the receipt of such notice or notices  relating
thereto,  Issuer shall deliver or cause to be delivered to the Holder the Option
Repurchase  Price and/or to the Owner the Option Share Repurchase Price therefor
or the portion thereof that Issuer is not then prohibited  under  applicable law
and regulation from so delivering.

                                       10

<PAGE>



      (c) To the  extent  that  Issuer is  prohibited  under  applicable  law or
regulation,  or as a consequence of administrative policy, from repurchasing the
Option and/or the Option Shares in full,  Issuer shall immediately so notify the
Holder and/or the Owner and  thereafter  deliver or cause to be delivered,  from
time to time, to the Holder and/or the Owner, as appropriate, the portion of the
Option  Repurchase  Price and the Option Share Repurchase  Price,  respectively,
that it is no longer prohibited from delivering, within five business days after
the date on which Issuer is no longer so prohibited;  provided, however, that if
Issuer  at any  time  after  delivery  of a notice  of  repurchase  pursuant  to
paragraph  (b)  of  this  Section  7  is  prohibited  under  applicable  law  or
regulation,  or as a consequence of  administrative  policy, or as a result of a
written agreement or other binding  obligation with a governmental or regulatory
body or agency,  from delivering to the Holder and/or the Owner, as appropriate,
the Option Repurchase Price and the Option Share Repurchase Price, respectively,
in part or in full (and Issuer  hereby  undertakes  to use its  reasonable  best
efforts to obtain all required  regulatory  and legal  approvals and to file any
required  notices  as  promptly  as  practicable  in  order to  accomplish  such
repurchase),  the Holder or Owner may revoke  its  notice of  repurchase  of the
Option  and/or  the  Option  Shares  either  in  whole or to the  extent  of the
prohibition, whereupon, in the latter case, Issuer shall promptly (i) deliver to
the  Holder  and/or  the  Owner,  as  appropriate,  that  portion  of the Option
Repurchase  Price  and/or the Option Share  Repurchase  Price that Issuer is not
prohibited  from delivering with respect to Options or Option Shares as to which
the Holder or the  Owner,  as the case may be, has not  revoked  its  repurchase
demand; and (ii) deliver, as appropriate,  either (A) to the Holder, a new Stock
Option  Agreement  evidencing the right of the Holder to purchase that number of
shares of Common Stock  obtained by  multiplying  the number of shares of Common
Stock for which the  surrendered  Stock Option  Agreement was exercisable at the
time of delivery of the notice of  repurchase  by a fraction,  the  numerator of
which is the  Option  Repurchase  Price  less the  portion  thereof  theretofore
delivered to the Holder and the  denominator  of which is the Option  Repurchase
Price,  and/or (B) to the Owner, a certificate  for the Option Shares it is then
so prohibited from  repurchasing.  If an Exercise  Termination  Event shall have
occurred  prior to the date of the  notice  by  Issuer  described  in the  first
sentence  of this  subsection  (c), or shall be  scheduled  to occur at any time
before the  expiration  of a period ending on the thirtieth day after such date,
the Holder  shall  nonetheless  have the right to exercise  the Option until the
expiration of such 30-day period.

      (d) For purposes of this Section 7, a  "Repurchase  Event" shall be deemed
to  have  occurred  upon  the  occurrence  of  any of the  following  events  or
transactions after the date hereof:


                                       11

<PAGE>



                  (i) the  acquisition  by any person (other than Grantee or any
      Grantee  Subsidiary)  of  beneficial  ownership of 50% or more of the then
      outstanding Common Stock; or

                  (ii) the consummation of any Acquisition Transaction described
      in Section  2(b)(i)  hereof,  except  that the  percentage  referred to in
      clause (z) shall be 50%.

      8. (a) In the event that prior to an Exercise  Termination  Event,  Issuer
shall enter into an agreement (i) to consolidate  with or merge into any person,
other than Grantee or a Grantee Subsidiary, or engage in a plan of exchange with
any person,  other than Grantee or a Grantee  Subsidiary and Issuer shall not be
the continuing or surviving  corporation of such  consolidation or merger or the
acquirer in such plan of exchange, (ii) to permit any person, other than Grantee
or a Grantee Subsidiary, to merge into Issuer or be acquired by Issuer in a plan
of  exchange  and Issuer  shall be the  continuing  or  surviving  or  acquiring
corporation,  but, in connection with such merger or plan of exchange,  the then
outstanding  shares of Common Stock shall be changed into or exchanged for stock
or other  securities  of any other  person or cash or any other  property or the
then  outstanding  shares of Common  Stock  shall  after such  merger or plan of
exchange represent less than 50% of the outstanding shares and share equivalents
of the merged or acquiring  company,  or (iii) to sell or otherwise transfer all
or a substantial part of its or the Issuer savings bank  Subsidiary's  assets or
deposits to any person, other than Grantee or a Grantee Subsidiary, then, and in
each such case,  the  agreement  governing  such  transaction  shall make proper
provision  so  that  the  Option  shall,  upon  the  consummation  of  any  such
transaction  and upon the terms and  conditions  set forth herein,  be converted
into, or exchanged for, an option (the "Substitute  Option"), at the election of
the Holder, of either (x) the Acquiring  Corporation (as hereinafter defined) or
(y) any person that controls the Acquiring Corporation.

      (b)         The following terms have the meanings indicated:

                  (i) "Acquiring  Corporation"  shall mean (i) the continuing or
      surviving  person of a consolidation  or merger with Issuer (if other than
      Issuer),  (ii) the acquiring  person in a plan of exchange in which Issuer
      is  acquired,  (iii) the Issuer in a merger or plan of  exchange  in which
      Issuer is the  continuing or surviving or acquiring  person,  and (iv) the
      transferee of all or a substantial part of Issuer's assets or deposits (or
      the assets or deposits of the Issuer savings bank Subsidiary).


                                       12

<PAGE>



                  (ii)  "Substitute  Common  Stock"  shall mean the common stock
      issued  by the  issuer  of the  Substitute  Option  upon  exercise  of the
      Substitute Option.

                  (iii) "Assigned Value" shall mean the  Market/Offer  Price, as
      defined in Section 7.

                  (iv) "Average Price" shall mean the average closing price of a
      share of the Substitute  Common Stock for one year  immediately  preceding
      the consolidation,  merger, share exchange or sale in question,  but in no
      event  higher than the closing  price of the shares of  Substitute  Common
      Stock on the day preceding such  consolidation,  merger,  share echange or
      sale;  provided that if Issuer is the issuer of the Substitute Option, the
      Average  Price shall be computed  with  respect to a share of common stock
      issued by the person  merging into Issuer or by any company which controls
      or is controlled by such person, as the Holder may elect.

      (c) The  Substitute  Option  shall  have  the same  terms  as the  Option,
provided that if the terms of the Substitute  Option cannot,  for legal reasons,
be the same as the Option,  such terms shall be as similar as possible and in no
event less advantageous to the Holder. The issuer of the Substitute Option shall
also enter into an agreement  with the then Holder or Holders of the  Substitute
Option in substantially the same form as this Agreement (after giving effect for
such  purpose  to the  provisions  of  Section  9),  which  agreement  shall  be
applicable to the Substitute Option.

      (d) The Substitute  Option shall be exercisable  for such number of shares
of Substitute  Common Stock as is equal to the Assigned Value  multiplied by the
number  of  shares  of  Common  Stock  for  which  the  Option  was  exercisable
immediately  prior to the event described in the first sentence of Section 8(a),
divided by the Average Price.  The exercise  price of the Substitute  Option per
share of  Substitute  Common  Stock  shall  then be equal  to the  Option  Price
multiplied  by a fraction,  the numerator of which shall be the number of shares
of Common Stock for which the Option was  exercisable  immediately  prior to the
event  described in the first  sentence of Section 8(a) and the  denominator  of
which  shall be the number of shares of  Substitute  Common  Stock for which the
Substitute Option is exercisable.

      (e) In no event,  pursuant to any of the foregoing  paragraphs,  shall the
Substitute Option be exercisable for more than 19.9% of the shares of Substitute
Common Stock  outstanding  prior to exercise of the  Substitute  Option.  In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of Substitute Common Stock outstanding prior to exercise but for this

                                       13

<PAGE>



clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash  payment to Holder equal to the excess of (i) the value of the
Substitute  Option  without  giving effect to the  limitation in this clause (e)
over  (ii)  the  value of the  Substitute  Option  after  giving  effect  to the
limitation in this clause (e). This difference in value shall be determined by a
nationally recognized investment banking firm selected by a majority in interest
of the  Holders  and the  Owners  and  reasonably  acceptable  to the  Acquiring
Corporation.

      (f) Issuer shall not enter into any  transaction  described in  subsection
(a) of this  Section 8 unless the  Acquiring  Corporation  and any  person  that
controls the  Acquiring  Corporation  assume in writing all the  obligations  of
Issuer hereunder.

      9.  (a) At the  request  of the  holder  of  the  Substitute  Option  (the
"Substitute  Option Holder"),  the Substitute Option Issuer shall repurchase the
Substitute  Option from the Substitute Option Holder at a price (the "Substitute
Option  Repurchase  Price") equal to the amount by which (i) the Highest Closing
Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute
Option,  multiplied by the number of shares of Substitute Common Stock for which
the  Substitute  Option may then be  exercised,  and at the request of the owner
(the  "Substitute  Share  Owner")  of shares of  Substitute  Common  Stock  (the
"Substitute  Shares"),   the  Substitute  Option  Issuer  shall  repurchase  the
Substitute Shares at a price (the "Substitute Share Repurchase  Price") equal to
the Highest  Closing  Price  multiplied  by the number of  Substitute  Shares so
designated.  The term  "Highest  Closing  Price" shall mean the highest  closing
price for  shares  of  Substitute  Common  Stock  within  the  six-month  period
immediately  preceding the date the Substitute Option Holder gives notice of the
required repurchase of the Substitute Option or the Substitute Share Owner gives
notice of the required repurchase of the Substitute Shares, as applicable.

      (b) Each Substitute  Option Holder and Substitute Share Owner, as the case
may be, may  exercise its  respective  rights to require the  Substitute  Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal  office,  the agreement for such Substitute  Option (or, in the
absence of such an agreement,  a copy of this Agreement) and/or certificates for
Substitute  Shares  accompanied by a written notice or notices  stating that the
Substitute  Option  Holder or the  Substitute  Share Owner,  as the case may be,
elects to require the  Substitute  Option  Issuer to repurchase  the  Substitute
Option and/or the  Substitute  Shares in accordance  with the provisions of this
Section 9. As promptly as practicable and in any event within five business days
after the surrender of the Substitute  Option and/or  certificates  representing
Substitute Shares and the receipt of such

                                       14

<PAGE>



notice or notices relating  thereto,  the Substitute Option Issuer shall deliver
or cause to be delivered to the Substitute  Option Holder the Substitute  Option
Repurchase  Price  and/or to the  Substitute  Share Owner the  Substitute  Share
Repurchase  Price  therefor or, in either case,  the portion  thereof  which the
Substitute  Option  Issuer  is not  then  prohibited  under  applicable  law and
regulation from so delivering.

      (c) To the extent that the  Substitute  Option Issuer is prohibited  under
applicable law or regulation,  or as a consequence of administrative  policy, or
as  a  result  of a  written  agreement  or  other  binding  obligation  with  a
governmental  or regulatory  body or agency,  from  repurchasing  the Substitute
Option and/or the Substitute  Shares in part or in full,  the Substitute  Option
Issuer shall  immediately  so notify the  Substitute  Option  Holder  and/or the
Substitute  Share Owner and  thereafter  deliver or cause to be delivered,  from
time to time, to the Substitute Option Holder and/or the Substitute Share Owner,
as appropriate, the portion of the Substitute Option Repurchase Price and/or the
Substitute  Share  Repurchase  Price,  respectively,   which  it  is  no  longer
prohibited  from  delivering,  within five business days after the date on which
the Substitute Option Issuer is no longer so prohibited; provided, however, that
if the  Substitute  Option  Issuer is at any time after  delivery of a notice of
repurchase  pursuant  to  subsection  (b) of this  Section  9  prohibited  under
applicable law or regulation,  or as a consequence of administrative  policy, or
as  a  result  of a  written  agreement  or  other  binding  obligation  with  a
governmental  or regulatory  body or agency,  from  delivering to the Substitute
Option Holder and/or the Substitute Share Owner, as appropriate,  the Substitute
Option Repurchase Price and the Substitute Share Repurchase Price, respectively,
in full (and the Substitute  Option Issuer shall use its reasonable best efforts
to  receive  all  required   regulatory  and  legal  approvals  as  promptly  as
practicable  in order to accomplish  such  repurchase),  the  Substitute  Option
Holder and/or  Substitute Share Owner may revoke its notice of repurchase of the
Substitute  Option or the Substitute  Shares either in whole or to the extent of
prohibition,  whereupon,  in the latter case, the Substitute Option Issuer shall
promptly (i) deliver to the Substitute  Option Holder or Substitute Share Owner,
as appropriate,  that portion of the Substitute  Option  Repurchase Price or the
Substitute  Share  Repurchase  Price that the  Substitute  Option  Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate,  either (A) to the
Substitute  Option Holder, a new Substitute  Option  evidencing the right of the
Substitute  Option  Holder to purchase  that number of shares of the  Substitute
Common  Stock  obtained by  multiplying  the number of shares of the  Substitute
Common Stock for which the surrendered  Substitute Option was exercisable at the
time of delivery of the notice of  repurchase  by a fraction,  the  numerator of
which is the Substitute Option

                                       15

Repurchase  Price  less  the  portion  thereof  theretofore   delivered  to  the
Substitute  Option Holder and the denominator of which is the Substitute  Option
Repurchase  Price,  and/or (B) to the Substitute  Share Owner, a certificate for
the Substitute Option Shares it is then so prohibited from  repurchasing.  If an
Exercise  Termination  Event shall have occurred prior to the date of the notice
by the  Substitute  Option  Issuer  described  in the  first  sentence  of  this
subsection (c), or shall be scheduled to occur at any time before the expiration
of a period ending on the thirtieth day after such date, the  Substitute  Option
Holder shall nevertheless have the right to exercise the Substitute Option until
the expiration of such 30-day period.

      10. The 30-day,  6-month,  12-month or  18-month  periods for  exercise of
certain rights under Sections 2, 6, 7 and 9 shall be extended: (i) to the extent
necessary to obtain all  regulatory  approvals  for the exercise of such rights,
and for the  expiration  of all  statutory  waiting  periods;  (ii)  during  the
pendency of any temporary  restraining  order,  injunction or other legal bar to
the  exercise  of such  rights;  and  (iii)  to the  extent  necessary  to avoid
liability under Section 16(b) of the Exchange Act by reason of such exercise.

      11. Issuer hereby represents and warrants to Grantee as follows:

      (a) Issuer has full  corporate  power and authority to execute and deliver
this  Agreement and to consummate  the  transactions  contemplated  hereby.  The
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated  hereby have been duly and validly  authorized by the
Issuer Board on or prior to the date hereof and no other  corporate  proceedings
on the part of Issuer are necessary to authorize this Agreement or to consummate
the  transactions  so  contemplated.  This  Agreement  has been duly and validly
executed and delivered by Issuer.

      (b) Issuer  has taken all  necessary  corporate  action to  authorize  and
reserve and to permit it to issue, and at all times from the date hereof through
the  termination  of this  Agreement  in  accordance  with its  terms  will have
reserved for issuance upon the exercise of the Option,  that number of shares of
Common  Stock equal to the maximum  number of shares of Common Stock at any time
and from time to time  issuable  hereunder,  and all such shares,  upon issuance
pursuant  thereto,  will  be  duly  authorized,   validly  issued,  fully  paid,
nonassessable,  and will be  delivered  free and  clear  of all  claims,  liens,
encumbrance and security interests and not subject to any preemptive rights.

      12. Grantee hereby represents and warrants to Issuer that:


                                       16

<PAGE>



      (a) Grantee has all requisite corporate power and authority to enter into,
execute and deliver this  Agreement  and,  subject to any  approvals or consents
referred to herein,  to consummate the  transactions  contemplated  hereby.  The
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate  action on the part of Grantee and no other  corporate  proceedings on
the part of Grantee are necessary to authorize  this  Agreement or to consummate
the  transactions  so  contemplated.  This  Agreement has been duly executed and
delivered by Grantee.

      (b) The  Option is not  being,  and any  shares  of Common  Stock or other
securities acquired by Grantee upon exercise of the Option will not be, acquired
with a view to the public  distribution  thereof and will not be  transferred or
otherwise  disposed  of  except  in a  transaction  registered  or  exempt  from
registration under the Securities Act.

      13.  Neither  of the  parties  hereto  may  assign  any of its  rights  or
obligations  under this Agreement or the Option  created  hereunder to any other
person,  without the express written consent of the other party,  except that in
the event a Subsequent Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its  rights  and  obligations  hereunder  within  six months
following such Subsequent  Triggering Event;  provided,  however, that until the
date 15 days following the date on which the applicable bank or thrift regulator
has  approved an  application  by Grantee to acquire the shares of Common  Stock
subject to the Option,  but only if such  approval is required,  Grantee may not
assign  its  rights  under the Option  except in (i) a widely  dispersed  public
distribution,  (ii) a private placement in which no one party acquires the right
to purchase in excess of 2% of the voting shares of Issuer,  (iii) an assignment
to a single party (e.g., a broker or investment  banker) for the sole purpose of
conducting a widely  dispersed  public  distribution on Grantee's behalf or (iv)
any other manner approved by the applicable bank or thrift regulator.

      14.  Each of Grantee and Issuer will use its  reasonable  best  efforts to
make all  filings  with,  and to  obtain  consents  of,  all third  parties  and
governmental  authorities  necessary  to the  consummation  of the  transactions
contemplated by this Agreement.

      15. (a) Grantee may, at any time following a Repurchase Event and prior to
the  occurrence  of an  Exercise  Termination  Event  (or such  later  period as
provided in Section 10),  relinquish the Option (together with any Option Shares
issued to and then owned by Grantee) to Issuer in exchange  for a cash fee equal
to the

                                       17

<PAGE>



Surrender Price (as hereinafter  defined);  provided,  however, that Grantee may
not  exercise its rights  pursuant to this Section 15 if Issuer has  repurchased
the Option (or any portion  thereof) or any Option Shares pursuant to Section 7.
The  "Surrender  Price" shall be equal to $4.4 million (i) plus, if  applicable,
Grantee's  purchase  price with respect to any Option Shares and (ii) minus,  if
applicable,  the excess of (A) the net cash amounts, if any, received by Grantee
or a Grantee  Subsidiary  pursuant to the arms' length sale of Option Shares (or
any other  securities into which such Option Shares were converted or exchanged)
to any  unaffiliated  party,  over (B) Grantee's  purchase  price of such Option
Shares.

      (b) Grantee may exercise its right to relinquish the Option and any Option
Shares pursuant to this Section 15 by  surrendering to Issuer,  at its principal
office, a copy of this Agreement  together with  certificates for Option Shares,
if any,  accompanied  by a written  notice  stating (i) that  Grantee  elects to
relinquish  the  Option  and  Option  Shares,  if any,  in  accordance  with the
provisions of this Section 15 and (ii) the Surrender  Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

      (c) To the  extent  that  Issuer is  prohibited  under  applicable  law or
regulation,  or as a consequence of  administrative  policy, or as a result of a
written agreement or other binding  obligation with a governmental or regulatory
body or agency, from paying the Surrender Price to Grantee in full, Issuer shall
immediately so notify  Grantee and thereafter  deliver or cause to be delivered,
from time to time, to Grantee,  the portion of the Surrender Price that it is no
longer prohibited from paying, within five business days after the date on which
Issuer is no longer so prohibited; provided, however, that if Issuer at any time
after  delivery  of a notice of  surrender  pursuant  to  paragraph  (b) of this
Section 15 is prohibited under applicable law or regulation, or as a consequence
of administrative policy, or as a result of a written agreement or other binding
obligation  with a  governmental  or regulatory  body or agency,  from paying to
Grantee the  Surrender  Price in full,  (i) Issuer shall (A) use its  reasonable
best efforts to obtain all required  regulatory and legal  approvals and to file
any required  notices as promptly as practicable in order to make such payments,
(B) within five days of the  submission or receipt of any documents  relating to
any such  regulatory  and legal  approvals,  provide  Grantee with copies of the
same,  and (c) keep  Grantee  advised of both the status of any such request for
regulatory and legal  approvals,  as well as any  discussions  with any relevant
regulatory or other third party reasonably  related to the same and (ii) Grantee
may revoke such notice of  surrender  by delivery of a notice of  revocation  to
Issuer and, upon delivery of such notice of

                                       18

<PAGE>



revocation,  the  Exercise  Termination  Event  shall be  extended to a date six
months from the date on which the Exercise Termination Event would have occurred
if not for the provisions of this Section 15(c) (during which period Grantee may
exercise any of its rights  hereunder,  including any and all rights pursuant to
this Section 15).

      16. The parties  hereto  acknowledge  that damages  would be an inadequate
remedy  for a breach of this  Agreement  by  either  party  hereto  and that the
obligations  of the parties  hereto shall be  enforceable by either party hereto
through  injunctive or other  equitable  relief.  In connection  therewith  both
parties waive the posting of any bond or similar requirement.

      17. If any term,  provision,  covenant or  restriction  contained  in this
Agreement  is held  by a court  or a  federal  or  state  regulatory  agency  of
competent  jurisdiction to be invalid,  void or unenforceable,  the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or  invalidated.  If for any reason such court or regulatory  agency  determines
that the Holder is not  permitted  to acquire,  or Issuer or  Substitute  Option
Issuer, as the case may be, is not permitted to repurchase  pursuant to Sections
7 or 9, as the case may be, the full number of shares of Common  Stock  provided
in  Section  l(a)  hereof (as  adjusted  pursuant  to Section  l(b) or Section 5
hereof),  it is the  express  intention  of Issuer  (which  shall be  binding on
Substitute Option Issuer) to allow the Holder to acquire or to require Issuer or
Substitute  Option Issuer,  as the case may be, to repurchase such lesser number
of shares as may be permissible, without any amendment or modification hereof.

      18.  All  notices,  requests,  claims,  demands  and other  communications
hereunder  shall be deemed to have been duly given when delivered in person,  by
fax,  telecopy,  or by registered or certified  mail  (postage  prepaid,  return
receipt  requested) at the respective  addresses of the parties set forth in the
Merger Agreement.

      19. This Agreement  shall be governed by and construed in accordance  with
the  laws of the  State of  Delaware,  without  regard  to the  conflict  of law
principles  thereof  (except to the extent that mandatory  provisions of Federal
law are applicable).

      20. This  Agreement may be executed in two or more  counterparts,  each of
which shall be deemed to be an original,  but all of which shall  constitute one
and the same agreement.

      21. Except as otherwise  expressly  provided  herein,  each of the parties
hereto shall bear and pay all costs and expenses

                                       19

<PAGE>



incurred by it or on its behalf in connection with the transactions contemplated
hereunder,  including  fees  and  expenses  of its  own  financial  consultants,
investment bankers, accountants and counsel.

      22.  Except  as  otherwise  expressly  provided  herein  or in the  Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the  transactions  contemplated  hereunder and  supersedes  all prior
arrangements or understandings with respect thereof,  written or oral. The terms
and  conditions of this  Agreement  shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assignees.
Nothing in this Agreement,  expressed or implied, is intended to confer upon any
party,  other than the  parties  hereto,  and their  respective  successors  and
permitted assignees, any rights,  remedies,  obligations or liabilities under or
by reason of this Agreement, except as expressly provided herein.

      23.  Capitalized terms used in this Agreement and not defined herein shall
have the meanings assigned thereto in the Merger Agreement.

      IN WITNESS  WHEREOF,  each of the parties has caused this  Agreement to be
executed on its behalf by its officers thereunto duly authorized,  all as of the
date first above written.

Plan, the Committee shall have sole and complete authority and discretion to (i)
select  Participants and grant Awards; (ii) determine the number of Shares to be
subject to types of Awards  generally,  as well as to individual  Awards granted

considered  to have been made under the Plan with respect to any Option or Right
which  terminates  and new Awards may be granted  under the Plan with respect to
the number of Shares as to which such termination has occurred.

Price of any Option or Right,  which shall not be less than the Market Value per
Share at the date of grant of such  Option or Right,  (ii) the  number of Shares

and rate (cumulative or otherwise) of exercise of such Option or Right, and (iv)
the restrictions,  if any, to be placed upon such Option or Right or upon Shares
which may be issued upon exercise of such Option or Right.

      Any Award made  pursuant to this Plan may, in the sole  discretion  of the
Committee,  vest in annual  installments  over a period of years, with the first
installment vesting on the one-year  anniversary of the date of grant, except in
the event of death or disability.

      Furthermore, at the time of any Award, the Participant shall enter into an
agreement with the Corporation in a form specified by the Committee, agreeing to
the terms and  conditions of the Award and such other matters as the  Committee,
in its sole discretion, shall determine (the "Option Agreement").

      7.     Exercise of Options or Rights.

            (a)   Except as provided  herein,  an Option or Right  granted under
                  the Plan  shall be  exercisable  during  the  lifetime  of the
                  Participant  to whom such Option or Right was granted  only by
                  such Participant and, except as provided in paragraphs (c) and
                  (d) of  this  Section  7,  no  such  Option  or  Right  may be
                  exercised unless at the time such  Participant  exercises such
                  Option or Right,  such  Participant has maintained  Continuous
                  Service since the date of grant of such Option or Right.

            (b)   To exercise an Option or Right under the Plan, the Participant
                  to whom such  Option or Right was granted  shall give  written
                  notice  to  the  Corporation  in  form   satisfactory  to  the
                  Committee  (and, if partial  exercises  have been permitted by
                  the Committee, by specifying the number of Shares with respect
                  to which such  Participant  elects to exercise  such Option or
                  Right)  together with full payment of the Exercise  Price,  if
                  any and to the extent required.  The date of exercise shall be
                  the date on which such notice is received by the  Corporation.
                  Payment, if any is required,  shall be made either (i) in cash
                  (including  check,  bank  draft or  money  order)  or,  if the
                  Committee in its discretion so determines,  (ii) by delivering
                  (A) Shares already owned by the  Participant and having a fair
                  market value equal to the applicable exercise price, such fair
                  market value to be  determined in such  appropriate  manner as
                  may be  provided  by the  Committee  or as may be  required in
                  order to comply  with or to  conform  to  requirements  of any
                  applicable laws or  regulations,  or (B) a combination of cash
                  and such Shares.

            (c)   If a Participant  to whom an Option or Right was granted shall
                  cease to maintain Continuous Service for any reason (excluding
                  death,   disability  and  termination  of  employment  by  the
                  Corporation or any Affiliate for cause), such Participant may,
                  but only within the period of three

                                        4

<PAGE>



                  months  immediately  succeeding  such  cessation of Continuous
                  Service  and in no event  after  the  expiration  date of such
                  Option or Right,  exercise  such Option or Right to the extent
                  that such  Participant was entitled to exercise such Option or
                  Right at the date of such cessation,  provided,  however, that
                  such right of exercise after  cessation of Continuous  Service
                  shall  not be  available  to a  Participant  if the  Committee
                  otherwise   determines  and  so  provides  in  the  applicable
                  instrument or instruments  evidencing the grant of such Option
                  or  Right.  If a  Participant  to whom an  Option or Right was
                  granted shall cease to maintain  Continuous  Service by reason
                  of death or disability  then,  unless the Committee shall have
                  otherwise  provided in the instrument  evidencing the grant of
                  an Option or Right,  all  Options  and Rights  granted and not
                  fully  exercisable  shall become  exercisable in full upon the
                  happening of such event and shall remain so exercisable (i) in
                  the event of death for the period  described in paragraph  (d)
                  of this  Section 7 and (ii) in the event of  disability  for a
                  period of one year  following  such  date.  If the  Continuous
                  Service  of a  Participant  to whom an  Option  or  Right  was
                  granted by the Corporation is terminated for cause, all rights
                  under any  Option or Right of such  Participant  shall  expire
                  immediately upon the effective date of such termination.

            (d)   In the  event  of the  death  of a  Participant  while  in the
                  Continuous  Service  of the  Corporation  or an  Affiliate  or
                  within the three-month  period referred to in paragraph (c) of
                  this Section 7, the person to whom any Option or Right held by
                  the  Participant  at the time of his death is  transferred  by
                  will or the laws of descent and  distribution,  or in the case
                  of an Award other than an Incentive Stock Option,  pursuant to
                  a qualified  domestic  relations order, as defined in the Code
                  or Title I of ERISA or the rules  thereunder  may, but only to
                  the extent such  Participant  was  entitled  to exercise  such
                  Option or Right upon his death as  provided in  paragraph  (c)
                  above,  exercise  such  Option  or Right at any time  within a
                  period  of one  year  succeeding  the  date of  death  of such
                  Participant,  but in no event  later  than ten years  from the
                  date of grant of such Option or Right.  Following the death of
                  any  Participant to whom an Option was granted under the Plan,
                  irrespective   of  whether  any   Related   Right  shall  have
                  theretofore  been  granted to the  Participant  or whether the
                  person  entitled to exercise  such Related Right desires to do
                  so, the Committee may, as an  alternative  means of settlement
                  of such Option, elect to pay to the person to whom such Option
                  is  transferred  by  will  or  by  the  laws  of  descent  and
                  distribution,  or in the  case  of an  Option  other  than  an
                  Incentive  Stock  Option,  pursuant  to a  qualified  domestic
                  relations order, as defined in the Code or Title I of ERISA or
                  the rules thereunder, the amount by which the Market Value per
                  Share on the date of exercise of such Option  shall exceed the
                  Exercise  Price of such  Option,  multiplied  by the number of
                  Shares   with   respect  to  which  such  Option  is  properly
                  exercised.   Any  such   settlement  of  an  Option  shall  be
                  considered  an exercise of such Option for all purposes of the
                  Plan.

      8. Incentive Stock Options. Incentive Stock Options may be granted only to
Participants  who are  Employees.  Any  provision  of the  Plan to the  contrary
notwithstanding,  (i) no  Incentive  Stock Option shall be granted more than ten
years  from the  date  the Plan is  adopted  by the  Board of  Directors  of the
Corporation  and no Incentive  Stock Option shall be  exercisable  more than ten
years from the date such  Incentive  Stock Option is granted,  (ii) the Exercise
Price of any Incentive  Stock Option shall not be less than the Market Value per
Share on the date such  Incentive  Stock Option is granted,  (iii) any Incentive
Stock Option shall not be transferable by the Participant to whom such Incentive
Stock  Option  is  granted  other  than  by  will or the  laws  of  descent  and
distribution, and shall

                                        5

<PAGE>



be exercisable during such Participant's lifetime only by such Participant, (iv)
no Incentive  Stock Option shall be granted to any  individual  who, at the time
such  Incentive  Stock Option is granted,  owns stock  possessing  more than ten
percent  of the  total  combined  voting  power of all  classes  of stock of the
Corporation or any Affiliate  unless the Exercise Price of such Incentive  Stock
Option  is at least 110  percent  of the  Market  Value per Share at the date of
grant and such Incentive Stock Option is not exercisable after the expiration of
five years from the date such  Incentive  Stock  Option is granted,  and (v) the
aggregate Market Value  (determined as of the time any Incentive Stock Option is
granted)  of the  Shares  with  respect to which  Incentive  Stock  Options  are
exercisable  for the first time by a Participant  in any calendar year shall not
exceed $100,000.

      9. Stock  Appreciation  Rights. A Stock Appreciation Right shall, upon its
exercise,  entitle the  Participant  to whom such Stock  Appreciation  Right was
granted to  receive a number of Shares or cash or  combination  thereof,  as the
Committee in its discretion shall determine, the aggregate value of which (i.e.,
the sum of the  amount of cash  and/or  Market  Value of such  Shares on date of
exercise)  shall  equal (as nearly as  possible,  it being  understood  that the
Corporation  shall not  issue any  fractional  shares)  the  amount by which the
Market  Value per Share on the date of such  exercise  shall exceed the Exercise
Price of such Stock Appreciation Right,  multiplied by the number of Shares with
respect of which such Stock  Appreciation  Right  shall have been  exercised.  A
Stock  Appreciation  Right  may be  Related  to an  Option  or  may  be  granted
independently  of any  Option as the  Committee  shall from time to time in each
case determine.  At the time of grant of an Option the Committee shall determine
whether and to what extent a Related Stock  Appreciation  Right shall be granted
with respect thereto, provided, however, and notwithstanding any other provision
of the Plan,  that if the  Related  Option is an  Incentive  Stock  Option,  the
Related  Stock  Appreciation  Right  shall  satisfy  all  the  restrictions  and
limitations of Section 8 hereof as if such Related Stock Appreciation Right were
an Incentive  Stock Option and as if other rights which are Related to Incentive
Stock Options were  Incentive  Stock Options.  In the case of a Related  Option,
such Related  Option shall cease to be  exercisable  to the extent of the Shares
with respect to which the Related Stock Appreciation  Right was exercised.  Upon
the exercise or termination of a Related Option,  any Related Stock Appreciation
Right  shall  terminate  to the extent of the Shares  with  respect to which the
Related Option was exercised or terminated.

      10. Limited Stock  Appreciation  Rights. At the time of grant of an Option
or Stock  Appreciation  Right to any Participant,  the Committee shall have full
and  complete  authority  and  discretion  to also grant to such  Participant  a
Limited  Stock  Appreciation  Right  which is  Related  to such  Option or Stock
Appreciation Right, provided, however and notwithstanding any other provision of
the Plan, that if the Related Option is an Incentive  Stock Option,  the Related
Limited  Stock  Appreciation  Right  shall  satisfy  all  the  restrictions  and
limitations  of Section 8 hereof as if such Related  Limited Stock  Appreciation
Right  were an  Incentive  Stock  Option  and as if all other  Rights  which are
Related to Incentive  Stock Options were  Incentive  Stock  Options.  Subject to
vesting  requirements  contained in 12 C.F.R. ss.  563b.3(g)(4) or any successor
regulation,  a Limited Stock Appreciation Right shall be exercisable only during
the period  beginning on the first day  following  the date of expiration of any
"offer" (as such term is hereinafter  defined) and ending on the forty-fifth day
following such date.


                                        6

<PAGE>



      A Limited Stock Appreciation  Right shall, upon its exercise,  entitle the
Participant to whom such Limited Stock Appreciation Right was granted to receive
an amount of cash equal to the  amount by which the "Offer  Price per Share" (as
such  term is  hereinafter  defined)  or the  Market  Value  on the date of such
exercise,  as shall have been provided by the Committee in its discretion at the
time  of  grant,   shall  exceed  the  Exercise  Price  of  such  Limited  Stock
Appreciation  Right,  multiplied  by the number of Shares with  respect to which
such  Limited  Stock  Appreciation  Right  shall have been  exercised.  Upon the
exercise  of a Limited  Stock  Appreciation  Right,  any Related  Option  and/or
Related Stock  Appreciation Right shall cease to be exercisable to the extent of
the Shares  with  respect to which such  Limited  Stock  Appreciation  Right was
exercised. Upon the exercise or termination of a Related Option or Related Stock
Appreciation Right, any Related Limited Stock Appreciation Right shall terminate
to the extent of the Shares with respect to which such Related Option or Related
Stock Appreciation Right was exercised or terminated.

      For the  purposes  of this  Section  10, the term  "Offer"  shall mean any
tender  offer  or  exchange  offer  for  Shares  other  than  one  made  by  the
Corporation,  provided that the  corporation,  person or other entity making the
offer acquires  pursuant to such offer either (i) 25% of the Shares  outstanding
immediately  prior to the  commencement of such offer or (ii) a number of Shares
which,  together with all other Shares  acquired in any tender offer or exchange
offer (other than one made by the  Corporation)  which expired within sixty days
of the  expiration  date of the  offer in  question,  equals  25% of the  Shares
outstanding  immediately prior to the commencement of the offer in question. The
term "Offer  Price per Share" as used in this  Section 10 shall mean the highest
price per Share paid in any Offer  which  Offer is in effect any time during the
period  beginning on the sixtieth day prior to the date on which a Limited Stock
Appreciation  Right is  exercised  and ending on the date on which such  Limited
Stock Appreciation Right is exercised. Any securities or property which are part
or all of the  consideration  paid for  Shares in the  Offer  shall be valued in
determining the Offer Price per Share at the higher of (A) the valuation  placed
on such securities or property by the corporation, person or other entity making
such Offer or (B) the  valuation  placed on such  securities  or property by the
Committee.

      11. Adjustments Upon Changes in Capitalization. In the event of any change
in the outstanding Shares subsequent to the effective date of the Plan by reason
of  any   reorganization,   recapitalization,   stock  split,   stock  dividend,
combination or exchange of shares,  merger,  consolidation  or any change in the
corporate  structure or Shares of the Corporation,  the maximum aggregate number
and class of Shares as to which  Awards  may be  granted  under the Plan and the
number,  class  and  exercise  price of  Shares  with  respect  to which  Awards
theretofore have been granted under the Plan shall be appropriately  adjusted by
the Committee, whose determination shall be conclusive.

      12.  Effect  of  Merger.  In the  event of any  merger,  consolidation  or
combination  of  the  Corporation   (other  than  a  merger,   consolidation  or
combination in which the Corporation is the continuing entity and which does not
result in the outstanding Shares being converted into or exchanged for different
securities,  cash or other property,  or any combination  thereof) pursuant to a
plan or agreement  the terms of which are binding upon all  stockholders  of the
Corporation (except to the extent that dissenting  stockholders may be entitled,
under  statutory  provisions  or  provisions  contained  in the  certificate  or
articles  of  incorporation,  to receive  the  appraised  or fair value of their
holdings),  any Participant to whom an Option or Right has been granted at least
six months prior to

                                        7

<PAGE>



such event shall have the right  (subject to the  provisions of the Plan and any
limitation or vesting period applicable to such Option or Right), thereafter and
during the term of each such Option or Right,  to receive  upon  exercise of any
such Option or Right an amount  equal to the excess of the fair market  value on
the  date  of such  exercise  of the  securities,  cash or  other  property,  or
combination thereof,  receivable upon such merger,  consolidation or combination
in  respect  of a Share  over  the  Exercise  Price  of such  Right  or  Option,
multiplied  by the number of Shares  with  respect to which such Option or Right
shall have been  exercised.  Such amount may be payable fully in cash,  fully in
one or  more  of  the  kind  or  kinds  of  property  payable  in  such  merger,
consolidation  or  combination,  or partly in cash and  partly in one or more of
such kind or kinds of property, all in the discretion of the Committee.

      13.  Assignments  and  Transfers.  No Award nor any right or interest of a
Participant under the Plan in any instrument evidencing any Award under the Plan
may be assigned,  encumbered or transferred except, in the event of the death of
a Participant, by will or the laws of descent and distribution or in the case of
Awards  other than  Incentive  Stock  Options  pursuant to a qualified  domestic
relations  order,  as  defined  in the Code or  Title I of  ERISA  or the  rules
thereunder.

      14. Employee Rights Under the Plan. No director, officer or employee shall
have a right to be selected as a Participant nor, having been so selected, to be
selected  again as a  Participant  and no director,  officer,  employee or other
person  shall have any claim or right to be  granted an Award  under the Plan or
under any other  incentive or similar plan of the  Corporation or any Affiliate.
Neither the Plan nor any action  taken  thereunder  shall be construed as giving
any  employee any right to be retained in the employ of the  Corporation  or any
Affiliate.

      15. Delivery and  Registration of Stock. The  Corporation's  obligation to
deliver Shares with respect to an Award shall, if the Committee so requests,  be
conditioned upon the receipt of a representation as to the investment  intention
of the Participant to whom such Shares are to be delivered,  in such form as the
Committee  shall  determine  to be  necessary  or  advisable  to comply with the
provisions of the Securities  Act of 1933 or any other  Federal,  state or local
securities legislation or regulation. It may be provided that any representation
requirement shall become  inoperative upon a registration of the Shares or other
action  eliminating the necessity of such  representation  under such Securities
Act or other securities  legislation.  The Corporation  shall not be required to
deliver any Shares  under the Plan prior to (i) the  admission of such shares to
listing  on any  stock  exchange  or other  system on which  Shares  may then be
listed,  and (ii) the completion of such registration or other  qualification of
such Shares under any state or Federal law, rule or regulation, as the Committee
shall determine to be necessary or advisable.

      16.  Withholding Tax. The Corporation  shall have the right to deduct from
all amounts  paid in cash with respect to the exercise of a Right under the Plan
any taxes  required by law to be withheld  with  respect to such cash  payments.
Where a Participant  or other person is entitled to receive  Shares  pursuant to
the exercise of an Option or Right pursuant to the Plan, the  Corporation  shall
have the  right to  require  the  Participant  or such  other  person to pay the
Corporation  the  amount  of any taxes  which the  Corporation  is  required  to
withhold with respect to such Shares, and may, in its sole discretion,  withhold
sufficient Shares to cover the amount of taxes which the Corporation is required
to withhold.

      17.  Amendment or  Termination.  The Board of Directors of the Corporation
may amend, suspend or terminate the Plan or any portion thereof at any time, but
(except as provided  in Section 11 hereof) no  amendment  shall be made  without
approval of the  stockholders  of the  Corporation  which shall (i) increase the
aggregate  number of Shares with  respect to which  Awards may be made under the
Plan,  (ii) materially  increase the benefits  accruing to  Participants,  (iii)
materially  change the  requirements as to eligibility for  participation in the
Plan or (iv) change the class of persons  eligible to  participate  in the Plan;
provided,  however,  that no such  amendment,  suspension or  termination  shall
impair  the  rights  of any  Participant,  without  his  consent,  in any  Award
theretofore made pursuant to the Plan.

      18.  Effective Date and Term of Plan. The Plan shall become effective upon
its ratification by stockholders of the Corporation. It shall continue in effect
for a term of ten years unless sooner terminated under Section 17 hereof.

         accelerate the time at which any or all of the restrictions shall lapse
         with respect to an Award, or to remove any or all of such restrictions,
         whenever it may determine  that such action is appropriate by reason of
         changes  in   applicable   tax  or  other  laws  or  other  changes  in
         circumstances  occurring  after  the  commencement  of such  Restricted
         Period.

(b)      Except as  provided  in Section 5 hereof,  if a  Participant  ceases to
         maintain  Continuous  Service  for any  reason  (other  than  death  or
         disability), unless the Committee shall otherwise determine, all Shares
         of Restricted Stock  theretofore  awarded to such Participant and which
         at the time of such  termination  of Continuous  Service are subject to
         the restrictions  imposed by paragraph (a) of this Section 3 shall upon
         such termination of Continuous Service be forfeited and returned to the
         Corporation.  If a Participant ceases to maintain Continuous Service by
         reason of death or disability,  Restricted  Stock then still subject to
         restrictions imposed by paragraph (a) of this Section 3 will be free of
         those restrictions.

(c)      Each certificate in respect of Shares of Restricted Stock awarded under
         the  Plan  shall  be  registered  in the  name of the  Participant  and
         deposited by the  Participant,  together with a stock power endorsed in
         blank,  with  the  Corporation,  and  shall  bear the  following  (or a
         similar) legend:

                  The  transferability  of this  certificate  and the  shares of
         stock  represented  hereby  are  subject  to the terms  and  conditions
         (including  forfeiture) contained in the 1998 Recognition and Retention
         Plan of Hudson River Bancorp,  Inc.  Copies of such Plan are on file in
         the offices of the  Secretary of Hudson River  Bancorp,  Inc., 1 Hudson
         City Center, Hudson, New York 12534.

(d)      At the time of any Award, the Participant shall enter into an Agreement
         with the Corporation in a form specified by the Committee,  agreeing to
         the terms and  conditions  of the Award and such  other  matters as the
         Committee,  in its sole  discretion,  shall determine (the  "Restricted
         Stock Agreement").

(e)      The payment to the  Participant  of  dividends  or other  distributions
         declared  or paid on such shares by the  Corporation  shall be deferred
         until the lapsing of the  restrictions  imposed under  paragraph (a) of
         this Section 3, and such dividends or other distributions shall be held
         by the Corporation for the account of the Participant  until such time.
         There shall be  credited  at the end of each year (or portion  thereof)
         interest on the amount of the deferred dividends or other distributions
         at a rate per annum as the Committee, in its discretion, may determine.
         Payment of deferred  dividends or other  distributions,  together  with
         interest  accrued  thereon,  shall be made upon the earlier to occur of
         the lapsing of the  restrictions  imposed  under  paragraph (a) of this
         Section 3 or upon death or  disability  of the  Participant.  Shares of
         Restricted  Stock subject to restriction on the date of any shareholder
         vote  shall  be  voted  by an  independent  party  to be  named  by the
         Committee.

(f)      At the lapsing of the  restrictions  imposed by  paragraph  (a) of this
         Section 3, the  Corporation  shall deliver to the Participant (or where
         the relevant  provision  of paragraph  (b) of this Section 3 applies in
         the  case  of a  deceased  Participant,  to his  legal  representative,
         beneficiary or heir) the  certificate(s) and stock power deposited with
         it  pursuant  to  paragraph  (c)  of  this  Section  3 and  the  Shares
         represented by such  certificate(s)  shall be free of the  restrictions
         referred to in paragraph (a) of this Section 3.

         4.  Adjustments  Upon  Changes in  Capitalization.  In the event of any
change in the outstanding Shares subsequent to the effective date of the Plan by
reason of any  reorganization,  recapitalization,  stock split,  stock dividend,
combination or exchange of shares,  merger,  consolidation  or any change in the
corporate structure or Shares of the Corporation, the maximum


<PAGE>



aggregate number and class of shares as to which Awards may be granted under the
Plan and the number and class of shares with respect to which Awards theretofore
have  been  granted  under  the Plan  shall  be  appropriately  adjusted  by the
Committee, whose determination shall be conclusive. Any shares of stock or other
securities  received as a result of any of the foregoing by a  Participant  with
respect to Restricted  Stock shall be subject to the same  restrictions  and the
certificate(s)  or other  instruments  representing or evidencing such shares or
securities  shall be legended and deposited  with the  Corporation in the manner
provided in Section 3 hereof.

         5. Assignments and Transfers.  During the Restricted  Period,  no Award
nor any right or  interest  of a  Participant  under the Plan in any  instrument
evidencing  any Award under the Plan may be assigned,  encumbered or transferred
except  (i) in the event of the death of a  Participant,  by will or the laws of
descent and  distribution,  or (ii) pursuant to a qualified  domestic  relations
order as defined in the Code or Title I of ERISA or the rules thereunder.

         6.  Administration.  The Plan  shall  be  administered  by a  Committee
consisting  of two or  more  members,  each  of  whom  shall  be a  Non-Employee
Director.  The  members  of the  Committee  shall be  appointed  by the Board of
Directors of the Corporation. Except as limited by the express provisions of the
Plan, the Committee shall have sole and complete authority and discretion to (i)
select  Participants and grant Awards; (ii) determine the number of Shares to be
subject to types of Awards generally, as well as individual Awards granted under
the Plan;  (iii)  determine the terms and conditions  upon which Awards shall be
granted  under  the  Plan;  (iv)  prescribe  the form and  terms of  instruments
evidencing such grants;  and (v) establish from time to time regulations for the
administration of the Plan, interpretation of the Plan, and determination of all
matters deemed  necessary or advisable for the  administration  of the Plan. The
Committee  may  maintain,  and update from time to time as  appropriate,  a list
designating  selected directors as Non-Employee  Directors.  The purpose of such
list  shall be to  evidence  the  status  of such  individuals  as  Non-Employee
Directors,  and  the  Board  of  Directors  may  appoint  to the  Committee  any
individual actually qualifying as a Non-Employee  Director regardless of whether
identified as such on said list.

         A majority of the Committee shall constitute a quorum,  and the acts of
a majority of the  members  present at any meeting at which a quorum is present,
or acts approved in writing by a ma jority of the  Committee  without a meeting,
shall be acts of the Committee.

         7. Shares  Subject to Plan.  Subject to  adjustment by the operation of
Section 4 hereof,  the maximum number of Shares with respect to which Awards may
be made under the Plan is 918,324.  The Shares with  respect to which Awards may
be made under the Plan may be either  authorized  and unissued  Shares or issued
Shares heretofore or hereafter  reacquired and held as treasury Shares. An Award
shall  not be  considered  to have been made  under  the Plan  with  respect  to
Restricted Stock which is forfeited and new Awards may be granted under the Plan
with respect to the number of Shares as to which such forfeiture has occurred.

         The Corporation's obligation to deliver Shares with respect to an Award
shall,  if the  Committee  so  requests,  be  conditioned  upon the receipt of a
representation  as to the investment  intention of the  Participant to whom such
Shares are to be delivered,  in such form as the Committee shall determine to be
necessary or advisable to comply with the  provisions of the  Securities  Act of
1933 or any other Federal,  state or local securities legislation or regulation.
It may be provided that any representation  requirement shall become inoperative
upon a registration  of the Shares or other action  eliminating the necessity of
such representation  under such Securities Act or other securities  legislation.
The


<PAGE>



Corporation  shall not be required to deliver any Shares under the Plan prior to
(i) the  admission  of such  shares to  listing on any stock  exchange  on which
Shares may then be listed, and (ii) the completion of such registration or other
qualification of such Shares under any state or Federal law, rule or regulation,
as the Committee shall determine to be necessary or advisable.

         8.  Employee  Rights Under the Plan.  No director,  director  emeritus,
advisory  director,  officer or employee  shall have a right to be selected as a
Participant nor, having been so selected,  to be selected again as a Participant
and no director, officer, employee or other person shall have any claim or right
to be granted an Award  under the Plan or under any other  incentive  or similar
plan of the Corporation or any Affiliate.  Neither the Plan nor any action taken
thereunder  shall be construed as giving any officer or employee any right to be
retained in the employ of the Corporation, the Bank or any Affiliate.

         9. Withholding Tax. Upon the termination of the Restricted  Period with
respect to any shares of Restricted Stock (or at such earlier time, if any, that
an election is made by the  Participant  under Section 83(b) of the Code, or any
successor  provision  thereto,  to include  the value of such  shares in taxable
income), the Corporation may, in its sole discretion,  withhold from any payment
or distribution  made under this Plan sufficient  Shares or withhold  sufficient
cash to cover any applicable  withholding and employment  taxes. The Corporation
shall have the right to deduct from all dividends paid with respect to shares of
Restricted  Stock the amount of any taxes which the  Corporation  is required to
withhold with respect to such dividend  payments.  No discretion or choice shall
be conferred upon any Participant with respect to the form,  timing or method of
any such tax withholding.

         10. Amendment or Termination. The Board of Directors of the Corporation
may amend, suspend or terminate the Plan or any portion thereof at any time, but
(except as  provided  in Section 4 hereof) no  amendment  shall be made  without
approval of the  stockholders  of the  Corporation  which shall (i) increase the
aggregate  number of Shares with  respect to which  Awards may be made under the
Plan,  (ii) materially  increase the benefits  accruing to  Participants,  (iii)
materially  change the  requirements as to eligibility for  participation in the
Plan or (iv) change the class of persons eligible


<PAGE>


to  participate  in  the  Plan;  provided,  however,  that  no  such  amendment,
suspension or termination  shall impair the rights of any  Participant,  without
his consent, in any Award theretofore made pursuant to the Plan.

         11. Term of Plan. The Plan shall become effective upon its ratification
by the stockholders of the  Corporation.  It shall continue in effect for a term
of ten years unless sooner terminated under Section 11 hereof.

                                     PART II

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20.          Indemnification of Directors and Officers.

         Article ELEVENTH of the Holding Company's  Certificate of Incorporation
provides for  indemnification  of directors and officers of the Holding  Company
against any and all liabilities,  judgments,  fines and reasonable  settlements,
costs,  expenses  and  attorneys'  fees  incurred in any actual,  threatened  or
potential proceeding,  except to the extent that such indemnification is limited
by  Delaware  law and such law cannot be varied by  contract  or bylaw.  Article
ELEVENTH  also  provides for the  authority to purchase  insurance  with respect
thereto.

         Section  145 of the  General  Corporation  Law of the State of Delaware
authorizes a  corporation's  Board of Directors to grant indemnity under certain
circumstances  to directors and  officers,  when made, or threatened to be made,
parties to certain  proceedings  by reason of such status with the  corporation,
against judgments,  fines, settlements and expenses,  including attorneys' fees.
In addition, under certain circumstances such persons may be indemnified against
expenses  actually and  reasonably  incurred in defense of a proceeding by or on
behalf  of  the  corporation.   Similarly,   the   corporation,   under  certain
circumstances,  is  authorized  to  indemnify  directors  and  officers of other
corporations  or  enterprises  who are  serving  as such at the  request  of the
corporation,  when such persons are made, or  threatened to be made,  parties to
certain  proceedings  by  reason  of  such  status,  against  judgments,  fines,
settlements  and  expenses,   including   attorneys'  fees;  and  under  certain
circumstances,  such persons may be indemnified  against  expenses  actually and
reasonably  incurred  in  connection  with  the  defense  or  settloement  of  a
proceeding  by  or in  the  right  of  such  other  corporation  or  enterprise.
Indemnification  is  permitted  where such  person (i) was acting in good faith;
(ii) was acting in a manner he  reasonably  believed  to be in or not opposed to
the best  interests of the  corporation or other  corporation or enterprise,  as
appropriate;  (iii) with  respect to a criminal  proceeding,  has no  reasonable
cause to believe  his  conduct  was  unlawful;  and (iv) was not  adjudged to be
liable to the corporation or other  corporation or enterprise  (unless the court
where the  proceeding  was  brought  determines  that such  person is fairly and
reasonably entitled to indemnity).

         Unless ordered by a court, indemnification may be made only following a
determination that such  indemnification is permissible because the person being
indemnified has met the requisite standard of conduct. Such determination may be
made (i) by the Board of directors of the Holding  Company by a majority vote of
a quorum consisting of directors not at the time parties to such proceeding;  or
(ii) if such a quorum  cannot be  obtained  or the  quorum so  directs,  then by
independent legal counsel in a written opinion; or (iii) by the stockholders.

         Section 145 also permits expenses incurred by directors and officers in
defending a  proceeding  to be paid by the  corporation  in advance of the final
disposition  of osuch  proceedings  upon the  receipt of an  undertaking  by the
director or officer to repay such amount if it is ultimately  determined that he
is not entitled to be indemnified by the corporation against such expenses.

Item 21.  Exhibits and Financial Statement Schedules.

         (a)      Exhibits.  See Exhibit Index
         (b)      Financial Statement Schedules.  Not applicable.
         (c)      Reports, Opinions or Appraisals.  Not applicable.

Item 22.  Undertakings.

(a)  The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

                  (i) To include any prospectus  required by section 10(a)(3) of
         the Securities Act of 1933;


                                      II-1

<PAGE>



                  (ii) To reflect in the  prospectus any facts or events arising
         after the  effective  date of the  Registration  Statement (or the most
         recent post-effective amendment thereof) which,  individually or in the
         aggregate,  represent a fundamental change in the information set forth
         in the  registration  statement.  Notwithstanding  the  foregoing,  any
         increase  or  decrease  in volume of  securities  offered (if the total
         dollar  value of  securities  offered  would not exceed  that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the  Commission  pursuant to Rule 424(b) (ss.  230.424(b)  of this
         chapter)  if,  in the  aggregate,  the  changes  in  volume  and  price
         represent no more than a 20% change in the maximum  aggregate  offering
         price set forth in the  "Calculation of Registration  Fee" table in the
         effective registration statement;

                  (iii) To include any material  information with respect to the
         plan of  distribution  not  previously  disclosed  in the  registration
         statement  or  any  material   change  to  such   information   in  the
         registration statement;

         (2) That  for the  purpose  of  determining  any  liability  under  the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (b) The undersigned  Registrant hereby undertakes that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

         (c) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus  which is a part of this  registration  statement,  by any  person or
party who is deemed to be an underwriter  within the meaning of Rule 145(c), the
issuer  undertakes that such reoffering  prospectus will contain the information
called for by the  applicable  registration  form with respect to reofferings by
persons who may be deemed  underwriters,  in addition to the information  called
for by the other Items of the applicable form.

         (d) The undersigned  Registrant  undertakes  that every  prospectus (i)
that is filed  pursuant to paragraph  (c)  immediately  preceding,  or (ii) that
purports to meet the  requirements of section 10(a)(3) of the Act and is used in
connection with an offering of securities  subject to Rule 415, will be filed as
a part of an amendment to the registration  statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933,  each such  post-effective  amendment shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (e)  Insofar  as  indemnification  for  liabilities  arising  under the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the registrant  pursuant to the foregoing  provisions,  or otherwise,
the  registrant  has been  advised  that in the  opinion of the  Securities  and
Exchange  Commission such  indemnification is against public policy as expressed
in the Act and is,  therefore,  unenforceable.  In the  event  that a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  registrant  in the  successful  defense of any  action,  suite or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.


                                      II-2

<PAGE>



         (f) The undersigned Registrant hereby undertakes to respond to requests
for information  that is incorporated by reference into the prospectus  pursuant
to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         (g) The undersigned  Registrant hereby undertakes to supply by means of
a  post-effective  amendment all information  concerning a transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.
